TV Tuners on GNU/Linux

[Joe Holloway]

I'm wanting to put a TV Tuner in my desktop at home.  Initially, I'd
like to be able to watch and record shows over TWC from my desktop,
but maybe long term have some kind of media center rig that I could
use to serve media out to other devices in the house.

Anyway, I'm having some analysis paralysis going over MythTV FAQs and
the like.  Was wondering if anyone had recommendations or experience
with a well-supported TV Tuner card on the more popular GNU/Linux
distros?  Can I pretty much pick from any of the newer Hauppauge
hardware?

I understand that to decode most HDTV I'd probably need a cable
receiver feeding into the tuner.  That's not a huge deal, but would
obviously be better without it.  I'd like to be able to watch and
record at the same time (I think), so I'd either need two cards or a
dual tuner, right?

Any general pointers?  I found some KCLUG discussions from a few years
back, but thought it might be worth asking again to get some more
current information.

Thanks,
Joe
