tv/fm card compatability with sv25 onboard video

[par]

i bought one of these boxes from a guy on anandtech for my sis's grad present. he's still waiting on my mo, so I don't have it yet; anyways..

i want to put a tv/fm cap card in there.. anyone know if there are any compatability issues?

has anyone had one of these boxes and made it an htpc with the onboard video? i've googled with no success, plz help if you can.

thanks!
