I pulled an old Hauppauge tuner card from a Gateway computer and hoped to use it along with my PVR250 as a second card. First of all I'm not even sure what model this is (I guess that's a bad omen of what's to come).
The tuner itself is plasted with "61381 Rev D423" and under that on the board is labeled 610000-08. Neither one of these really matches any numbers on Hauppage's website. It has a radio and IR plug and one labeled DTV/S-vid (you can get digital video through the s-video plug on this

)
So anyways I put this thing in my box (1.8ghz Althon XP, 256mb ram, geforce2, 30gb drive) along with my PVR250. My first question is how do you know which card is which when you are configuring them? video0? video1? video36? It seems like a guessing game. Same goes for the dsp and other drivers it asks for. Maybe I need to check the MythTV site for this? I haven't gotten to far with that yet. I assume I got at least one of them right since I was able to get live video on the screen.
First time I tried configuring the MPEG2 driver first and that seems to make MythTV use that card first then use the BTTV-based card when necessary. With this setup I was able to record video and watch live tv until I went to change the channel. It seems like the frontend would halt when I went to go to any other channel besides the default.
I then tried running setup again setting the BTTV tuner up first. I again tried recording one channel and watching another and as long as the BTTV tuner was recording it appeared to work well. I then went to watch the recorded show and it had no audio though (I had audio previously when it was being used live I think). When the show was done recording and I tried to change channels it again started locking up.
So I'm at a loss on what to do besides keep reading more forums and messing with config files, or maybe trying to compile the latest version of MythTV (which supposedly fixes some live tv freezing problems, but I haven't successfully got past the compilation errors). For now I'll go back to the single PVR250 card and deal with not watching TV while it's recording. If you guys have any help I'd appreciate it though. Thanks.
