manual makes no mention of being able to use a line interrupt to run a routine function or procedure so i guess turning the screen offnis not poss i was hoping the atom lite might stand a chance if i figured out how to chop the screen$ into ½ screens though i would have needed tops and bottoms then she maybe could load 12KB in stead of full 24KB and would have upped the frame rate a bit especially if teh screen was switched off for a½ the asic waits sates too instead of just loading half the screen - was going to try to use cyberlink power director or intervideo wincoder winproducer though i still have no software for teh msi nvidia fx5900zt vtd 128 VIVO despite having asked a few times over the past few years - mind you the drivers on their site are still as reliable as pouring a hot cup of coffee in the power supply(DO NOT DO THIS AT HOME OR IF YOU ARE UNDER A BRIDGE)
