You're probably right, at least for modern devices. It was several  
years ago that I was playing with this on my Zaurus and I was using  
full-resolution DVD rips and they were causing pauses and audio sync  
problems, probably due to CPU limitations as you indicated.

This was also MPEG-2 not MPEG-4, although MPEG-4 takes more  
processing power there is less data that has to be moved processed,  
the Zaurus had some problems with transfer speed to and from the SD

Sounds interesting. The truth is these little devices are fun to play  
with but I have found that I really don't want to watch a video on a  
tiny screen when away from home - a book is more entertaining and  
doesn't have the battery life problems of a video player :-)
