Comment:

 OK. I will guess that something is overwriting the frame's buffer space
 and clobbbering videobuffers queue management?
 Could I get someone to turn the Vector-enhanced setting back on after
 applying this patch:
 {{{
 % svn diff yuv2rgb.cpp
 Index: yuv2rgb.cpp
 ===================================================================
 --- yuv2rgb.cpp (revision 11063)
 +++ yuv2rgb.cpp (working copy)

  #endif

  #ifdef MMX
 -    return mmx_yuv420_2vuy;
 +    //return mmx_yuv420_2vuy;
  #endif

      return non_vec_yuv420_2vuy; /* Fallback to C */
 }}}
 which will tell us if QuickTime is screwing up the frontend's data, or if
 the MMX routine is. And the output from -v playback would be helpful, too.
