[MPlayer-users] seg fault in quicktime

Thu Jan 31 23:54:11 CET 2008

I've been using mencoder for the last while now, but some recent movies I'd
downloaded are getting a segmentation fault for some reason, can someone
provide some insight?
I'm running as root and other videos have converted, so is there something
special about quicktime?
