What my plan is:
Bravia connects to home theatre via HDMI to get the TheatreSync
then PS3 connects to the second HDMI port on Bravia
For the sound, PS3 will output to the Analog Audio IN (red & white analog) on the DVD player (of the home theatre set).
Since the normal range of home theatre does not have optical or hdmi IN, I'll have to use the analog cable. Not sure whether the home theatre will upmix the 2.0 signal into good quality 5.1?
Do you think its possible to setup this way?
