[Mp4-tech] MPEG4 problem with the new Quicktime (7.1.3)

[Mor Sela]

Hi all,
I had a working encoder for mp4 until the new version of quicktime
(7.1.3) was published.
Now, every time I try to open one of the mp4 I have created, quicktime
just exits with an 'Error -2010: The movie contains some invalid
data', which actually was a problem I thought I had solved when 7.0.3
came out (which was with the decspecificinfo). I guess the problem
here must be similar to the problem with the previous version. Does
anybody has any idea where could the problem be or even happen to
experience that problem?
Thanks.
