B U S T E R R E A D M E F I L E March 17, 1997 ---------------------------------------------------------------------- This document reflects technical changes to the Buster product from its previous release. ---------------------------------------------------------------------- Buster Drivers V: 1.019 Multimedia Navigator II V: 1.003 NOTE: This release is a matched pair. Different versions of Multimdia Navigator II will not operate properly with different versions of Buster Drivers. To determine which version of the drivers you are running, open the Windows Explorer, locate the BUSTER.DLL file in the C:\Windows\System directory, click on it with the right mouse button, select Properties, and select the Version tab. If you are upgrading from a previous installation of Buster, your Multimedia Navigator II .INI file must be removed to upgrade properly. The install script will take care of this automatically for you by deleting the following file: C:\WINDOWS\MMNAV.INI Removing this file will delete your TV Channel settings, so be sure to rerun AutoScan to locate all of your available channels again. To begin the upgrade, follow the procedure listed below: 1. Select CONTROL PANEL from the SETTINGS list in the START menu. 2. Double-click on the SYSTEM icon, then select the DEVICE MANAGER tab. 3. Locate the SOUND, VIDEO, and GAME CONTROLLERS listing, and single-click on the BUSTER II entry. 4. Click on the PROPERTIES button, and then the DRIVER tab. 5. Click on the CHANGE DRIVER button, and then the HAVE DISK button to initiate the new installation. 6. Various requesters will pop up during the install procedure that simply require you fill in the drive letter for your CD-ROM and click on OK. At the end of this process, your system will restart and the new Buster drivers will be installed. 7. Now proceed to install the new Multimedia Navigator II by inserting the Multimedia Navigator II Install CD into the CD-ROM drive, select RUN from the START menu, type "D:\setup" in the command line box and click on OK. (You need to substitute the appropriate driver letter if your CD-ROM drive is not drive D:.) Additional driver updates may be posted on the Quadrant International web site (http://www.qi.com) from time to time. ---------------------------------------------------------------------- C H A N G E S I N T H I S R E L E A S E 1. Detects DirectX 1.0 and reports an error instead of crashing 2. Added specific channel lists for Australia, Italy, and Ireland 3. Installation of the Teletext font is more robust 4. Added support for 8-bit VGA modes using DirectDraw with Hardware Overlay support 5. A Plug and Play VxD problem when sharing IRQs was fixed 6. Bugs in the MCI commands for setting/getting color saturation and tint (hue) were fixed 7. Teletext decoding has been completely re-written; this eliminates problems experienced with PAL-I teletext and improves overall performance 8. Resources for localization added (first ports: German & Japanese) 9. MCI Interface has been expanded/stabilized; documentation will be made available in the near future 10. A bug in loading/saving environment files was fixed 11. An option to MUTE audio when Multimedia Navigator II is minimized has been added. Previously audio was not muted unless manually muted. 12. A panic "Boss Key" has been added to minimize the Multimedia Navigator window (in any mode) and mute the audio. This key is F12. You can restore Multimedia Navigator II to its previous state by single-clicking on its minimized button in the Windows 95 Taskbar. 13. Default Capture/Scratch file set to Windows 95 $TEMP directory as CAPTURE.AVI 14. To exit out of TopMost Window mode or Full Screen mode, you can hit the ESCAPE key, or single-click the RIGHT mouse button. 15. Menu items reorganized to more logical locations 16. The Frequency Tables have been improved (AutoScan finds more valid channels) 17. The unused ENVIRONMENT window no longer opens when an environment is opened. By default, a VideoIN window is opened, although this can be changed by opening a different window and saving the environment. 18. If non-default wallpaper is selected and the file is corrupt, the default will be used 19. A pop-up window size indicator has been added to all video windows; it is visible just below the lower-right corner of the window when it is being resized 20. NTSC-Japan and PAL-I standards implementation improved 21. The maximum frequency while auto-scanning NTSC-US was increased to 885.25 MHz + 3.0 MHz 22. The maximum frequency while auto-scanning all PAL standards was increased to 895.25 MHz + 3.0 MHz 23. In NTSC, the top 21 lines of video per frame contain timing and other synchronization information which appears are random pixels at the top of the image in a TV Window. These lines are now cropped out of the display window. 24. The Options dialog box, General tab was revised to make it less ambiguous about when a custom Background was being used and when the default Background was being used. 25. The Stream Capture Toolbar and Snapshot menu were revised to position the buttons and menu items in order of most common use (i.e. sort of a step 1, step 2, step 3, step 4 order). 26. DirectDraw is now supported. Machines with complete DirectDraw VGA drivers in their systems (and enough VGA display memory on their VGA cards) will be able to view full-screen TV or video, and it will be scaled to full-screen -- no black borders. Note: DirectDraw hardware scaling requires a VGA chip capable of scaling in hardware, and approximately 0.5MB of VGA RAM to perform the scaling, which means 2MB VGA cards will need to run at about 800x600 to leave enough RAM free for scaling. To use higher resolutions with full-screen scaling, you will need at least 4MB of VGA RAM. If there is not enough memory for scaling, or your graphic chip lacks hardware scaling capabilities, the display defaults to its previous method of displaying the video at its maximum standard size (NTSC or PAL) and centering it on a black screen. 27. Closed Captioning text is cleared whenever a channel is changed, including multi-channel scan. Previously, if Closed Captioning text was displayed and the channel was changed to a channel that did not carry Closed Captioning, the previous text would be left over. Other strange effects occured in multi-channel scan mode. 28. Additional internal changes were made to improve the stability and performance of this product. 29. Help Files updated and integrated into Multimedia Navigator II. 30. Special .INI file entry added for ET6000-based VGA cards. See known issues below for more information. 31. Items that aren't available when video capture is enabled are grayed out in the menus. ---------------------------------------------------------------------- KNOWN ISSUES AND NOTES: 8-bit Modes This driver supports 8-bit (256-color) video modes, but when Multimedia Navigator starts, a advisory message will appear. If you want to use 8-bit mode, you can ignore the message and continue, and everything should work properly. The message will not appear in hi-color or true-color modes. Window Size Indicator In Windows 95, the window size indicator that appears when resizing will indicate the original size of the window, before the resizing, only when the mouse is released at the completion of the resizing. This is because Windows 95 does not signal mouse movement events to the Buster driver. To work around this and produce an exact-sized window, you can resize the window by one pixel after you get it to the proper size, using the pop-up to confirm the size is correct. Windows 95 Plus, and later versions of Windows which send more message to installed drivers do not have this problem, so the pop-up will be updated continuously to reflect the current size of the window. Changing or Resizing the Selected Window when Video Capture is Enabled In some cases, enabling video capture restricts the driver's ability to control and reprogram certain hardware registers in the Buster card. Users should select the intended sources, and properly size the selected preview window before enabling video capture. If you experience minor problems when selecting other windows or resizing them, or adding new windows after video capture has been enabled, simply turn off video capture, then adjust the windows, then enable video capture again. Number of Reserved DMA Memory Pages In the Custom tab of the Buster driver, a default value of 256 pages (1 Meg) of DMA memory is allocated. This value was chosen to avoid consuming memory resources (higher values could affect system performance when the system doesn't have a lot of memory installed), but is not sufficient to capture single frames at full size. If your system has 16M or more memory, you should increase this value to 300 pages to allow capturing full-screen (720 by 480 at 24-bit color depth). Additional benefits are not gained by increasing the value beyond 300 pages. Compression Method Not Preserved From One Capture Session To Another Unlike the other capture parameters, the choice of compression method (either a Codec or Full Frames [Uncompressed]) is not preserved if video capture is disabled and then re-enabled. You need to set the compression method each time video capture is enabled, unless you are using the first one in the list. This reverting to the first item in the list is a Windows 95 issue and cannot be corrected in the Buster driver. Performance Problems or Sluggish Video Capture Start Most problems with system performance, responsiveness, and delays between the time you press "OK" to start capturing and when the capturing actually begins to record frames can be attributed to insufficient system memory. These issues are not related to the Buster driver; rather they are Windows memory management or Video for Windows issues. It is highly recommended to install at least 16M, and preferably 32M, of system memory and to use a high performance motherboard (such as the Intel Triton HX) for video capture whenever possible. ET6000 and DirectX DirectX (DirectDraw) drivers for various VGA cards (most notably those based on the Tseng Labs ET6000 chip) sometimes overlay video on top of all graphics, including dialog boxes and the mouse pointer. This can make it difficult to access certain menu items or dialog boxes unless you move the video window out from on top of the item you need to access. The live video would overwrite the menu item, preventing it from being the topmost item. If you cannot move the window out of the way, or are having significant problems using your computer when DirectX (scaled) video windows are active, you can modify an entry in the C:\WINDOWS\BUSTER.INI file to enable a workaround in the Buster driver to handle these VGA cards. Load the C:\WINDOWS\BUSTER.INI file into a text editor and locate the section header [PIPConfig]. If there is an entry in that section labelled "NoDDClipper=0" change it to "NoDDClipper=1" to enable the workaround. If this entry is not present, add it on a blank line in the [PIPConfig] section. For example: [PIPConfig] ...other entries... NoDDClipper=1 ...other entries... To disable this workaround at anytime in the future, change this line to "NoDDClipper=0". NOTE: You must reboot after any changes to the Buster .INI file for the changes to take effect. Tseng Labs regularly updates its display drivers, which are available for download on their web site at http://www.tseng.com Users should always check for later display card drivers (regardless of VGA card manufacturer) and test them if problems are observed. ---------------------------------------------------------------------- ###Download Driver Pack
