* demux_avi sets stream_delay according to dwStart * mplayer adjusts audio_delay according to stream_delay 3 related patches are pending, and I will apply them over the next few days if all goes well. As I mentioned on -dev-eng, the funny indentation is in preparation for one of those pending patches.
