the crash occurs at 8:29 in the clip "test.rm" (when the guy starts to shoot arrow). i tracked it down to "stream_read" function in stream.h, which causes a buffer overflow. (len bigger than buffer), i hope this info helps. if i skip over that frame, it will play fine. MPlayer versions tested: 5pre, 6pre, mingw32 CVS build of 15 march 2005. PS: when i play this clip in "media player classic" it will show a short error in the frame, but it doesnt crash the player.
