As above. I am connecting a ps3 to my optoma hd65 via the above amp. connecting straight from the ps3 to the projector via hdmi is fine...every time... which rules out the pj and ps3. However, connecting via the amp and i get intermittent problems. The ps3 seems to connect to the amp (the hdmi caption flashes then locks on and the 7.1 channels illuminate (pcm) ok. However, turn on the pj and the amp and ps3 disconnect from each other (the 7.1 channel icons disappear and it loses the pcm caption). no image is output obviously. This leaves me to think that it's no probs with the ps3 or pj as connected directly they are fine. Any settings on the amp i need to change?? I have had it work ok once and it didnt have probs. but next time i tried using system i have to cycle through inputs etc etc and its pure fluke when it works.
