QuickTime does not support HDR images. But I assume you mean you are
outputting a tone mapped panorama, which is just a regular LDR image?
Can you render the same QTVR on your windows and mac machines and post
both, so we can see the problem? You can share large files through
(e.g.) http://ge.tt/

QuickTime 7 (which is the latest Windows version) still supports QTVR files.
