hello again. I've got my htpc basically doing everything i think it should be (including standby sorted

), but now that i have it hooked up to my M series samsung lcd i've been trying a few diferent things as far as getting hd-wmv to play, without success.
The issue is that there is what looks to be a diagonal glitch through the screen from top to bottom,doesn't matter if the vid is full screen or windowed it's still there The panel is fine as it plays bluray via a ps3 no worries.
I've tried both purevideo and cyberlink decoders, different refresh rates and pretty much everything i can think of.
could it be that the onboard x1250 just doesn't cut the mustard when it comes to 1080p.
does any one have any ideas or should i admit defeat and buy a 2600xt, (which creates other issues)
TIA
