Also, most of the surround files I come across are AAC or AC3, and reencoding them hurts the audio quality too much. Vorbis is attractive because it is open source with no strings attached, but AAC encoding and decoding support is strong and unlikely to vanish anytime soon.

Indeed, I think it's more of a bias on my part. LC-AAC and vorbis (encoded via aoTuV) should give similar results at bitrates above 128kbps, but I have a natural tendency to use vorbis anyway. I don't exactly have a target bitrate, but I'd like an audio encode to be as transparent as practically possible. Dealing with captures, I'd stick with the original encoded track if possible.
