thanks, yes that is probably it. would a gt430 improve things ?. i had 
read a prior thread here that said the 610 could nearly do advanced 2x, 
so i thought even without the advanced 2x it would be sufficient for 
fairly smooth playback. the files from my hdpvr play mostly acceptable, 
those are a slightly lower bit rate. was hoping i was missing something 
that would improve things. i am on .27 playing to a samsung 40 inch 
display a couple of years old, d630. i had to do a lot of tweaking to 
get xbmc to play smoothly, but now it is smooth on hd content.
