[MPlayer-users] [Bugreport] Dxr3 and qt

[Anders Rune Jensen]

Hi

I got quicktime working fine on my laptop so I thought I would try it
on my dxr3. It played fine for about 2 min, then mplayer crashed. The
crash happens exactly at the same point in the movie, no matter if I
just let it play or I fast-forwards to the place where it crashes. I
recompiled with debug and a full gdb bt is at the buttom of this mail.

I really hope this helps.

mplayer -vo dxr3 -vop lavc TheTwoTowers-tlr_480.mov
