You should not change the extension of a file just like that. A .mp4 file is an MPEG-4, that although looks like a QuickTime movie, it's not. It's similar to grabbing a text file (.txt) and giving it a Word extension (.doc); similar in some senses, but not the same.
If you want to compress a QuickTime movie with the MPEG-4 codec go through the export process, but instead of selecting "Movie to MPEG-4" select "Movie to QuickTime Movie", click on the "Options" button and select the MPEG-4 codec.
This will indeed create a QuickTime movie which should have a .mov extension, but compressed with the MPEG-4 codec.
The difference between a MPEG-4 file and a QuickTime file is that QuickTime is proprietary and for the most part requires QuickTime to be installed. MPEG-4 is a standard format, that at least in theory, could be played by other players; not only QuickTime.
Unfortunately you're seeing a case where some people don't have MPEG-4 players, which is exactly the opposite of what MPEG-4 stands for.
