hello all. so i just got an ati 4890, and when i watch dvds (from the original disc) the picture seems a "little fuzzy and blocky". for example when it goes into a red or dark background you can literaly see tiny blocks, and the peoples faces seem a little fuzzy. before i got this card i was using my nvidia 8800gt and all the dvds i played then were crystal clear, no blocks no fuzzyness. ive looked into the avivo settings and messed with every other setting in ati controle center and nothing helps. is there anything i can do that im not thinking of? i thought ati was good for home theatre and HD playback, but so far my 8800gt seems to be better. please help me, as i would like to have this $200 card look better than my old 8800gt. thanks so much
