Has anyone used this format successfully with the Onkyo TX-SR700? I waited to buy the Onkyo because of the earlier DD EX drop-out problems. This receiver works fine on the problem discs, but does not detect EX mode on the newer DD EX discs. I have to force the EX mode on, but feel the sound is being manipulated and not truly working as intended. I would like to leave the receiver in "Auto" mode and see it detect DD EX when present. Some examples are Star Wars Episode I and Monsters Inc. Both are DD EX. If I leave the receiver in auto, the rear center channel is not active. Any ideas?
