This has been driving me nuts since I'm fairly sure my PC should handle this without too many issues. 1st off the rig AMD 64 X2 4200+ ATI X850 256Mb PCI-E 2Gb DDR RAM 36.5Gb Sata drive (OS) 4 x 500Gb Samsung Spinpoints (SATA) Auzen X-Mystique 7.1 Gold Running Win XP 32 sp2 and Meedio frontend. The Board does have space for 2 DDR2 sticks so I'll try that 1st off but i'm getting really bad stutter on 1080p and more importantly getting stutter on high action scenes in 720p I can live without 1080p since theres barely any discernable difference on a 42" screen but 720p is too damn important. Anyone got any ideas??
