I've been searching the forums and haven't found any information on how to troubleshoot this issue. My ATV2 is connected to a receiver via Toslink. I've ripped a few dvd's using HB's latest and greatest ATV preset, but the ATV is only passing the DPLII audio track. The ATV2 intro shows 5.1 on the receiver and I believe HD rentals are working as well. Any thoughts?
