I can't find a definite answer to this question either. I hate to be a total noob but anyways. I have a Twinhan VP 1025 in already and I have a Hauppage Win-TV go Plus (for cable). They both have a connexant 878 chipset though. Although the Win-TV is a 878A. Is this possible or will it cause damage. The reason I am asking is because I am almost sure that I read something about this being a bad idea but I can't find nothing now.

There should be no problem, I have 2x Nova-Ts.

I have three air2pc cards. Each card will work independently so you shouldn't have a problem with that. The only thing to consider is that lots of cards together can maybe generate too much heat. Also, if you don't have a good coax connection and use a splitter you might lose too much signal strength. Multiple cards is one of Mythtv's strong points, so go for it!
