I seem to remember I saw fixed PES size (for the video) in some digital 
tv channels, so I assume this is acceptable... But I might be wrong

I suspect you forgot the biggest problem: DTSs are never set... At 
least, last time I checked the PES header was filled with PTSs only. I 
do not think this was ok for a lot of clients. I'll double check tomorrow.
