Also, just a note for people since I see many complaints about TV tuners.
TV broadcasts here in the states uses NTSC, which is a significantly lower resolution than a monitor. So, when a small video is enlarged to full screen, there will be pixellation, and it will look fairly bad but some tuners have filters where the fullsize window will look half decent. So, just something to keep in mind.
Anyway, I have the Ledtek PVR2000 and its great. It was one of the few tuners that I could find that supports full Stereo audio output on the TV & FM tuner.
