The non ability of the "default" surround mode to retain it's setting has me very disapointed as well. It appears when, for instance, I set "upsample" for my one of my inputs. If I only send PCM to the acciociated optical input, all is well. But the moment that input gets some other type of data stream, it changes the "default"! Now, if I later send PCM to that input, I get PL2 as the mode. Compounding this problem, There is no good way to see the current surround mode without changing modes!
Sure, if I set "vidio 1" to be DD+PL2Music, and set "vidio 4" to be upsample, and both use the same toslink in, the "default" works IF and only IF the datastream is the correct format, forever. But don't allow it to change; in my case I use a Dish 921, and I like the 48k PCM music channels on "vidio 4 upsample". BUT, we change channel to a movie; Boom, no more default if we return to PCM later. The same issue can be expected for a DVD player used for PCM and DD/DTS.
I REALLY, REALLY would like to have this change. Is there anyone I could pay off to help get the ball rolling on this a bit sooner?
