Quicktime player not referencing mp4 files

[stgoldberg at aol.com]

The problem I am having is that  when I use the Quicktime player in a stack and want to reference a movie choose "all files", mp4 files are greyed out and cannot be selected.  With Livecode version 5.5.2 (on Mac OS10.6.8) I can only select .mov files.  However, when using another computer that has Mac OS 10.7.5 and Livecode version 5.5.3, I can make the mp4 selection.  Am I doing something wrong?  Does Livecode 5.5.2 differ in its ability compared to Livecode 5.5.3?  Or could the difference be the different Mac OS systems?
Thanks.

Import as control a video that is MP4 does seem to fail. Placing a video control 
and trying to select an MP4 shows as grayed out if you choose QuickTime files, 
but if you choose All Files, then the MP4 hooks up and plays fine.
