with AVI you have some buffer which contains part of the file, simply 
check the frame size, if you have enough pass a pointer to the decoder, 
if not read more

with MPEG-PS you need to do the same but additionally you need to
go over all the data and ensure that you have a complete slice before
you can decode it, or is there some trick iam not aware of?

MPEG-PS is also much more tricky to generate, its trickier to store 
non-mpeg video/audio in it, it has more space overhead ...
