HVR-1600 No signal issue

[Endymion]

Hey all,

Has anyone else had issues with their HVR-1600 coming up with "No Signal" when you try to tune an open QAM channel in Sage? I have the latest driver off the Hauppage site, and Sage 6.2.8. I had scanned the channels in Sage 6.2.6, then remapped the physical channel to a lineup with the HD program information for COX. That all worked fine. Then I had problems where I would change to one of the QAM channels in the Sage program guide, and the tuner would either be stuck at the last channel it was tuned to, or it would say "No signal". Each time I could go in and edit the channel lineup, and from there view a QAM channel and it would work fine. Then when I went back to the program guide and tuned from there, it would work OK for awhile and then "No signal" again. After awhile, it just stopped working all together.

I've tried to see if I can tune the channels with WinTV, but I can't seem to get the damn thing to work. It doesn't even seem to see the tuner at all. What am I doing wrong?
