Ok, I made some more test and the problem doesn't seems to be related to
quicktime, but to the snapshop function on Lion.
I tested with LC 4.6.3 on Lion with the following code:
Put the rect of [image | player | button] "foo" into tRect
Export snapshot from rect tRect to file "export.png" as [PNG | JPEG]
Exporting a snapshot of an image or player object (with assigned image/video
file) results in corrupted image data (stripes, black,...)
Exporting a snapshot of a button works fine as expected.
Could anybody please confirm this as a bug or point me on what I am not
