OS X (10.4.7) - Upside down movies

1
Using the newest version of OS X + the newest version of matlab and PTB (beta), I get the
following odd behavior when playing QT movies. The movies appear upside down. It is like
this in our code and using the QuickTimeDemos included with PTB. Mpeg movies play fine, as
do other QT movies. But this particular set of movies (from iMovie) get displayed inverted.
Thoughts? Ideas?

Thanks, Mike

Update: I've updated to OS-X 10.4.7 and Quicktime 7.1.2 - Same result. The movie plays
at proper orientation, assuming that the greeble(?) shows a human like figure with the
head and eyes?/eyebrows? at the top.

So it is not a bug in the most recent PTB or recent OS-X / QT. Maybe you need to reinstall
/ repeat the update, whatever...

Another possibility could be a bug in the gfx-driver or QT when interacting with the gfx-
driver. Then it would be a bug in QT or gfx-driver that only shows up with specific
models/brands of gfx-cards... Mine is a NVidia GeforceFX 5200...

Sorry, can't be of more help, maybe you want to upload the movie to the forum and others
can test if it is something hardware specific?
