It's important to balance the audio and video quality. I can't think of much more annoying things than having awesome audio and blocky shit video, or good video and 56kbps MP3 audio (ala default Fraunhofer encoder, which I've seen people use before).

I've heard about people having filesize nightmares with multi-channel Vorbis, so what profile and/or bitrate would you recommend for AAC if I want transcode and have no noticeable loss of quality?
