Bose V20 Issue

Hello all...

In the last week, I've completed upgraded my HT system. The TV has gone from an older 32" 1080i Sony HDTV to a 46" 1080p XBR4. The sound has gone from an older 5.1 Sony Receiver to a Bose V20 setup. So far I love the way everything looks and sound, but I'm having one issue that's kind of frustrating.

I have both the BDP-S300 and HD-A20 connected to the receiver running the audio through HDMI. No issue with the S300 as it outputs a perfect 5.1. But the A20 only displays as PCM 2.0. I've tried pretty much everything I can think of from switching to optical to achieve 5.1 (the method I used with the older receiver), to switching the input (the V20 Receiver has an HDMI input for either the 'DVD' or 'CBL/SAT'.) Neither results in any success.

I've also tried adjusting the settings on the A20 menu. Digital HDMI is set to 'Auto' and SPDIF is set to PCM (tried Bitstream with no avail).

Any ideas or thoughts?

Thanks!

SPDIF is set to Bitstream and still no luck. I have the optical cable connected, but I think I either need to mess around more with the settings (not too sure what to mess around with as I feel like I've tried everything) or I'll call customer service as many have said that they're actually helpful.
