Possible things I can think of:
1) Bug in MPlayer's http implementation corrupts data
2) Playing via http results in using a different demuxer
3) Bug in http server
4) Random changes in memory layout might result in just decode errors instead of crashes.

Do you get decode errors? If so, do you also get them when playing the file locally?
