6 VidLet Release Notes
========================================================================
v1.66 - Added Closed Captioning support with scalable fonts
- Added Active Video Detection of video plugged/unplugged
- VidLet is using dark magenta as color key for overlay on
graphics. Current revision of the RIVA TNT Display Drivers
are dithering this color during blitting. This results in
a non uniform key area and therefore the video is intermixed
with graphics. This problems occures only on certain display
color modes and should be fixed soon by nVIDIA.

- Improved Closed Captioning Display
- Compatibility with Telecaptioning 1/2/3
- Worked around the color key problem of v1.66
v1.68 - CC-Decoder reset on too many parity errors
- Horizontal cropping on all Platforms (configurable with itt.ini)
- On disabling the overlay paint the window black. This eliminates the
magenta flashes on reinitialzing size or format
- CC performance from a macrovision source improved
- CC Display will work now, even if Intercast or WaveTop is not installed
- Recover from lost surfaces in capture driver
v1.71 - VidLet does not minimize on Tuner source
v1.72 - Added support for all RIVA TNT2 derivatives
========================================================================
7 Teletext Browser Release Notes
========================================================================
v1.0 - Release version, no new versions are planned
========================================================================
8 Notes for Microsoft NetMeeting users
========================================================================
NetMeeting v2.0 and v2.1 uses a database of optimal seetings
for registered video cards.
If this card is not a registered one then NetMeeting will
default to sub-optimal settings overriding the defaults
of the capture driver.
To overcome the problem you have to install the capture
driver after the NetMeeting installation.
========================================================================

Intel Intercast 1.1/1.2/1.3/1.5/1.6 and 2.0/2.1
