I just got off the phone with Tosiba technical support about a possible bug with the A3 displaying 2CH when it should be displaying MULTI..
I have my A3 audio set to Bitstream for Digital Out SPDIF and PCM for Digital Out HDMI.. I am connecting to a Pioneer VSX-1015TX receiver via optical out..
My A3 displays 2CH on the front status screen and my receiver shows THX CINEMA with 5.1 channels coming in.. The digital signal settings on the receiver are set to Auto.. If I change the SPDIF to PCM, it chooses DDPLII MV+THX instead of THX CINEMA..
Now in the A3 manual it states that if it shows 2CH its outputting 2 channels and if it shows MULTI its outputting multi-channel sound..
Toshiba tech is sending me new firmware v2.5 for the A3, so while its not on the website yet, be on the lookout for it or call tech support so they can mail it to you.. They claim it fixes numerous audio and video issues..
So this is a PRE-announcement to firmware v2.5.. Should I get it before its released on the site, Ill post a link here..
