Cleared this up for myself and post here for the records.

Apparently, for mp4, mplayer has 2 demuxers available, lavf and mov.
As of now, the latter takes edit lists/delayed starting times into
consideration, the former does not. The whole point is that the
default demuxer seems to have changed since rc2, from mov to lavf.

Use of a specific demuxer can be forced of course, also for
verification of above observations, as I did:
mplayer -demuxer lavf clip.mp4
mplayer -demuxer mov clip.mp4
