When using an MP4 file in page editor, I get a black screen and have to force close Acquire Editor using the Task Manager. Why does this occur?
We would recommend not to use QuickTime coded videos (if possible). In testing and client environments they have been known to be at the root of memory leaks within PC based systems.
If you have no choice and are unable to have the videos re-rendered in another format such as DivX, then we would recommend manually uninstalling the QuickTime application from the affected PC, reboot the PC and install a fresh copy of the QuickTime application direct from the Apple website. This should resolve any issues with the playback of the affected MP4 files.
