Hi, Last weekend i bought a Samsung 40" 6 series TV, it looks great, i have a Samsung 5.1 home theatre system set up to it, an xbox 360, and a wii, but i wanted to connect a htpc to it as well, im on a budget at the moment so i built a pc out of components from old pcs, and bits that were lying around. CPU: FX-55 Mobo: MSI K8N Diamond Plus SLi mother board GFX: XFX 7900GTX (have got 2, but didnt bother adding the second one in) RAM: 2GB OCZ Platinum memory Unfortunately i cant seem to get any hardware acceleration working on the 7900 and the CPU doesnt really seem up to 1080p, i tried updating the drivers and it went very wrong, so i had to revert back to the drivers that came with the card. Does anyone have any suggestions, either for a different gfx card, i dont want to spend much though, or a way to get DXVA working. Would using Vista Premium work any better than XP? Also, when i installed WMP11 it got a little bit further before stuttering.
