Keep away from MPEG 4
Fact is I can not see it at all with my QT 6.5.2 OSX 10.3.9
Have no idea why. My system is just updated to 10.3.9 but not to QT 7
Movie is black.
I tried to make one earlier today and I thought it had to do with
CubicConverter but it is the same with your test.
I believe the basic installation on Windows does not have it but it
should be no problem on Mac.
I tried it several years ago and found the quality to be unuseable.
Sorensen 3 is the only alternative and in some cases it can spare about
10% download.
