I hate to tell you that, but I guess the only solution to trace the
problem is just to follow the instructions that are displayed when
MPlayer crashes; that is, recompile with debug symbols, and do a gdb
backtrace.
You can find more details here:
http://www.mplayerhq.hu/DOCS/HTML/en/bugreports_what.html#bugreports_crash

You might also want to upload a 1-2 Mb sample (just make sure this
sample triggers the same problem on CVS and plays fine with -pre6) to
ftp://mplayerhq.hu/MPlayer/incoming/ as maybe there are issues with
your file, but I doubt it.

There might be better solutions than this, but I truly don't know.

Regards,
Guillaume
