Apologies... I keep trying to change my profile, and it never seems to "stick"!
Its an Intel 24" iMac, running 10.5.1
The surround sound is a Sony home theatre set up, with an integrated woofer/amp and five satellites.
I have connected it using the optical connection (inside headphone socket on iMac) and alternatively using USB. The USB level is much lower, and I can't get the surround at all, so I'm now using only the optical.
If I set the DVD player preferences to "digital output" rather than "System sound", then I get surround sound out of the home theatre setup, but only when playing directly in DVD Player. If I use Front Row, then it reverts to regular stereo, using the woofer the two L and R speakers.
It surprises me, because I assumed Front Row was just a "menu" and used the various media player apps to actually playback the content. It's as if some Front Row setting was overriding the DVD player preferences. The first thing I'll try when I get back home to the computer is trashing the Front Row plist file, after checking that DVD Player is still set to digital output...
bestest,
M.
