crash when playing with some subtitles

this issue is a dup of issue#160.

i tried the latest code r968 which picks up the updated mplayer-mt binary in 
r959, but the mplayer still crash with the same assertion failure.

also i tested the mplayer SVN snapshot at HEAD on  2010-11-28, the video played 
just fine.

it confused me, so i replaced the mplayer-mt  binary with the one compiled from 
mplayer SVN HEAD , but mplayer terminated itself, i found it was due to the 
incompatible options of ass-margin-top/bottom. after hacking a little bit, 
mplayer did not complain the command line options any more, instead it failed 
to load the video with following message

MPlayer interrupted by signal 6 in module: decode video
- MPlayer crashed. This shouldn't happen.
  It can be a bug in the MPlayer code _or_ in your drivers _or_ in your
  gcc version. If you think it's MPlayer's fault, please read
  DOCS/HTML/en/bugreports.html and follow the instructions there. We can't and
  won't help unless you provide this information when reporting a possible bug.
2010-11-29 01:50:58.673 MPlayerX[84103:a0f] terminated:1 

so i guess it could be the difference between mplayer-mt and mplayer, and then 
tried to compile a mplayer with ffmpeg-mt, but stopped by some annoying 
problems on Mac.

zongyao, could you please show me the ropes on how to get a working mplayer-mt 
for mplayerx or update the binary in repository with a recent version of 
mplayer?  i agree with your that issue#160 was fixed in mplayer upstream, but 
it would be great if we can benefit from it.

thanks for your great job. =)
