yeah, both good suggestions.
As I just recently upgraded my windows machine and reinstalled windows 
and then dsmyth, I cannot try these yet because now any player will 
crash when trying to play nuv files!  I suspected the open from backend 
would help, and maybe transcoding to mpeg4 with smaller file sizes.  The 
crashing problem is a windows thing, so once I solve that I will retest 
it.  thanks
