Ask Slashdot: Linux and TV Tuner Cards

Paul Moore wanted some help on TV Tuner cards. He writes: "I have a few questions that I was hoping you or the slashdot community would be able to answer. Basically I am looking into picking up a TV card for my machine, but I had a few questions about the capabilities of the bttv/video4linux stuff and didn't want to waste the developer(s)' time by mailing the video4linux list..." There's more! You know what to do...

"...Here are my questions (any help is greatly appreciated) :

1. Which card is best supported (which is easiest to setup and get working)? I am currently looking at the Hauppauge WinCast/TV-radio (model 401), but I remember hearing that it had a slightly different chip on it, has this been taken care of yet? Do people have this working?
2. In the future (read when I am able to save up some $$$) I am thinking on slapping another monitor on my system - how does the TV card handle multiple heads?
3. I am currently running 2.0.35, what do I need to get it running bttv? When 2.2 is released will I still need bttv or is video4linux built in? Also, what programs do people recommend to watch TV?
4. Lastly, anybody know where I can get a real deal on the Hauppauge card :)

Thanks for all your help!"
