Yes,
QT can run even 4 movies like this (I duplicated the file and checked).
Anyway, I think I have found the bug. I forgot to activate the following
line in case the client_Storage extension is supported.
glPixelStorei(GL_UNPACK_CLIENT_STORAGE_APPLE, GL_FALSE);
Now I can quite run 4 movies at the same time. Fiuuuuu.
For a while I thought the G5 was..., but it is still my great Mac.
Only, I think, and when the client_Storage extension is not supported? Poor
users.
Thanks to all of you. Great list.
Best Regards
