Ye right. Thought it was libquicktime because it used to crash on the
same interlaced video height resolutions not being mod32
situations. In demux_mov.c now I read heroine though. Either way, it
was the default mp4 demuxer in rc2, and it handled edit list
atoms. The current default, lavf, does not. That was the whole point.

Sure, when I come around to it. I believe it's a known issue though,
as there have been page long discussions on the handbrake forums about
mplayer not correctly handling their video due to it's ignoring edit
lists.

It's been about mp4, by the way, not particularly about quicktime.
