>From what I recall, in many places MOV does use PASCAL strings (length
+ non \0), while MP4 changed this to be C strings (\0 terminated),
which is about the only significant difference (sometimes I wondered if
it's not just to crash MOV parsers).
I don't have time, but you'll definitely want to check both QT and MP4
specs for this.
