I just setup my new TCP50VT25 last night. I connected my PS3, via HDMI, using digital out to my pre-amp. I can not get anything but 2 Ch out of the PS3. Before yesterday, I was using an external box to pull the audio from the HDMI. I have tried setting the audio output to HDMI, manual, double digital, DTS, and PCM out... But, oohing but 2 CH. My pre-amp says is is only getting 2CH PCM. Any thoughts? I am tired of having that extra box, as it causes connection problems.. Thanks.
