[quote=cvmom]We also use PlayOn with a Wii to stream to TV. Getting along without cable just fine.

Anyone care to share more about the TV tuner with a PC option? Where do you buy such a TV tuner, and how hard to install?[/quote]

Here’s something to get you started. Eye tv has good reviews. A lot of the functionality of a TV tuner depends on the DVR software you get.
