Okay, here is the deal, I have an ATI TV Wonder Pro TV tuner, and I remember that a while ago (Sabayon 3 or so) there was a TV application that worked perfectly with my card.
I recently installed the Sabayon 4 Lite MCE on my secondary machine, which now has that TV tuner in it, though I notice that this version of Sabayon no longer contains that TV software.
I have done an emerge search for "tv", but I only got two results and neither of them seem to be it.
emerge -s tv
header files for DVB
(no idea what this is.)
Edit- Doh! Forgot to --sync!
