emotiva umc-1 issues

i recently purchased aumc-1 after owning a denon 3803 because i wanted to experiment into the dedicated pre/pro world. i currently setup with adcom apms 5500/5503, paradigm speakers/sub, panansonic 50" plasma, ps3, direct tv, and panamax conditioner. after listening to the umc-1 i hear an improvement in sound quality and clarity, the video processing is good too, but am having troubles with the sound modes, i can not get dolby digital surround from my ps3, only stereo and direct modes are available. i am hooked up through monster 2000 hdmi cables and can not get any surround from the ps3 to show up as an available mode on the umc-1. i have read many issues with this preamp and am having some audio drop out but overall i like it. it has latest firmware 7.04 i just cant figure out how to get more sound modes available from the umc-1. most of the sources i have tried only stereo and direct modes are available, no true dolby or truehd. any suggestions or comments would be appreciated. thank you.
