  One would think a properly written utility would figure out how to 
automatically adjust frame rates (to skip a frame now and then) to 
present the most decent video possible given various hardware and 
environmental limitations.  The N800 seems to attempt to work this way 
for video streamed off the internet, but not taken off it's internal 
memory card.  Also, video streamed off the net isn't resized to full 
screen, while video from the internal card is forced into full screen 
display without any user options. 

  I'd be happy if given an option to display the video at it's native 
size.  When my 512x288 at 29fps mp4 video is scaled to full wide screen, 
the video details are lost as well as is overall viewability.  It chops 
the audio into short blips while individual video frames take 5 or more 
seconds to load.  While the N800 doesn't technically lock up, the home 
screen becomes unaccessible so killing the essentially locked up video 
player is difficult to impossible without rebooting the machine.  At 
least when trying to view this particular video.
