I just bought a Hauppauge 150 w/o MCE and am having the same problems with the channels locking in on Cable TV.
This is what I've observed so far, using the latest Hauupauge drivers and also the Beta version for the 150.
1) When I change stations, it seems to lock in good for a split second and then goes fuzzy/black&white, just like what the pics in this thread show.
2) Only 2 stations(Ch#14 and Ch#16) lock in clear. Not sure why these 2 work
3) I get the same results when I use the "Tuning Assistant"
4) However, if I use the Tuning Assistant and choose "Antenna" instead of Cable, the first 13 stations lock in perfectly and then 14-73 are empty/snow.
5) When I record in GBPVR, the same distortion shows up
6) WinTV2000 works perfectly for all stations - viewing and recording
Is there any way to do a manual scan within GBPVR, similar to WinTV2000?
