[mythtv-users] PVR-150/500 and bttv?

[Michael Tiller]

I don't think I'm gonna be much use here because I can't help you with most 
of the technical details but I can say that I have run a BTTV and a PVR-150 
at the same time. One thing I found (in fact, about the only I can add that 
might help you) was that the order of the cards in the PCI slots made a 
difference. Unfortunately, I can't tell you what particular configuration 
worked, only that it made a difference in my case.

An additional thing to note is that I was not at all with the quality of the 
captures I got from my BTTV. The quality of the signal just seemed really 
bad when it came through the BTTV card. In fact, I was so dissatisfied with 
it that I turned it off.

I don't know if the BTTV card just sucked (it was a Win-TV card) or if there 
was some kind of interference with the PVR-150?!? If anybody knows of a 
reason why the presence of the PVR-150 should make the BTTV signal suck and 
knows a way to address the problem, I'm all ears.
