When using my AIW 8500DV system compatibitlity test with version 7.5 it says my sound card clock stability is out of spec with a .5%...when I upgrade to 7.7 it says i pass with less than .2 but I still get audio sync problems. I am using a Turtle Beach Santa Cruz as my sound card on an Athlon 1ghz...why does my sound card have audio sync problems? Is there anything not too expensive i can buy to get rid of these annoying problems that occur in any program when i go from MPEG2 to DVD format...
