Anyone else make any progress on this?

I was digging around, looking for information on the Quicktime
libraries, and found that both VLC and mplayer have the same crash
when in quartz mode.  Of course, they have OpenGL display modes, so
they can still work in a MacOS environment, so noone has been working
toward a fix in those apps.

I'm still looking around for more info on the Quicktime side, and
looking for an example app that actually works using
'DecompressSequenceFrameWhen'.   But, I haven't found anything yet.
