Sync should be perfect: --fifodir uses a clever algorithm, inserting a few extra frames or dropping the odd one so that the audio and video will remux perfectly. There can be slight glitches at cut points, but --cleancut can prevent those. There was a bug for a while that could mess up the sync when transcoding MPEG streams, but that seems to be fixed now on the 0.25 branch.

I didn't realise there was any transcode method that preserved cc.
