I would get an AIW, but since this will be on a primarily Linux machine and Linux and ATI don't mix so well (or it's at least makes more work than I want to go through to get it working good) I want something that won't be terribly hard to configure.
cheztir, that box looks nice, but sadly, anything over about $40 is too much for my budget.
I will probably buy a TV tuner card soon (meaing in the next month hopefully) and I will try to get it working on my current Linux machine. If it doesn't work, I will just have to use XP since I plan on dual-booting just not using XP for much other than games.
But thank you for all the help everyone!
