Well, the results are in and I guess I have to eat crow (yuk)
I tried both the SatCruiser DSR-ACE and an EmTech receiver (both with digital audio outputs) and neither one would pass Dolby Digital
AC3 on the
PBS channels on AMC 3. My Denon receiver did an auto lock on PCM when I connected the
satellite receivers' optical output to it so I guess that answers
that question...
But I discovered one neat thing -- digital audio sounds a heck of a lot better than standard audio even on regular stereo channels !! :P
