Well, it's sort of working. Yes, the AC3 sound is now passed to the optical port. BUT, non-AC3 sound shows mixed results. Some sound is passed through the optical port, some through RCA R/L, and almost none through coax.
No sound, for example, is passed for any channels, with the exception of the California Channel and NYS Legislature on AMC1-C via coax or RCA. I e-mailed Pansat with the question about the non-AC3 sound issues. Their response was that they tested their equipment with RCA and it worked OK. No reference to coax.
So signal passed via coax to other rooms remain soundless with this firmware version. I guess I am now in the market for a new receiver (probably not Pansat). I've read many reviews, but am wondering if anyone can provide personal, positive receiver experience.
Thanks and Merry Christmas.
