When the picture-in-picture turns on, the audio switches from 5.1 surround to 2.0 surround, whether or not the material in the small window has audio or not. I tried pressing every button and combination on the Playstation 3 remote and could not switch back and forth between the main feature audio and window audio. When sketches appeared in the window, the receiver switched to 2.0 and went dead quiet. I even tried switching the PS3 audio output between LPCM and Bitstream and it made no difference.
Well this part of the review was very disheartening, but hopefully that will be limited to just this one movie, and not something they can't fix.
