Saw a few comments asking about scheduling into Matrox G450 eTV. Volunteered to help and quickly had 4 people interested enough to help in the investigation and testing.
Cannot load the eTV software onto local PC - too many checks for hardware being present - so relying on others to collect data and then try things out.
Once the first registry dumps came through it took about 20 minutes to have the basics coded. Unfortunately it crashs the eTV software.
Might have to go to see someone that has one of these TV cards to get to the bottom of it.
