Hi, im digging this one up from the dead but anyways. I just got an Advanced A/V pack myself and i have the s-video and the toslink/optilcal cable hooked up as well. The only problem is that i can only select Dolby Pro-Logic not Digital. I read above that there was a bug in all the first Xbox games and they are only 4.1, is this the reason for me only being able to select pro-logic?
