I installed various render profiles but some profiles are still inactive (greyed out)HDV, AVIDV, to name a few
these profiles have other issues however MPEG-4 unsupported audio codec, H.264 unsupported video codec, flash unsupported audio codec:libmp3lame, to also name a few. What can I do to make these work?
UPDATE
I downloaded again the Youtube 720p optimized profile, and I made sure I had libx264 installed, it is there! I get the Unsupported video codec: libx264 error still. Anyone???

Guess no one knows, really! What is it with you Linux people anyway, every question I posted here has gone unanswered. what is up with that?
