Not sure what you mean by "general", but it seems I said svn.

Again, it depends on the mp4 demuxer. In rc2, it defaults to mencoders
own mov/mp4 demuxer, which does take account of elst atoms. In svn
though, somewhere along the way, the lavf demuxer was made the
default, and that one does not honor edit lists. Obviously, the
latter is a known issue, as it has been noted on that ffmpeg task
list.

The reason I mentioned it here was just to prevent people wasting time
when it turns out that the MP4Box delay parameter has no effect
whatsoever on playback with mplayer svn, *unless* they explicitly turn
on the internal mov demuxer. Apart from that I didn't suggest
anything, as far as I can tell.
