There are a bunch of channels on C-band, although mainly on DVB-S2, and you run into some on DBS sats. Not too many on regular Ku, but it's becoming more and more common. You're definately going to need mpeg4 pretty soon, as it is becoming more and more popular.coolsat 8000 is one of them
not much mpeg4 on fta though
but considering the DBS sats are subscription only again not much for the true FTA'er
