Hello. I purchased a HK 225 from Sound City and just got it today. I hooked everything up and set up the inputs, levels, etc... However, when I was testing the actual programming, I tried to watch a program on my satellite receiver. I have the Philips directv/tivo receiver. I have it connected to the 225 by an optical cable. My problem is this: When I start with a regular non-Dolby Digital broadcast, the DPLII kicks in and everything is fine. When I switch to a DD broadcast, everything is still fine. However, when I switch back to a non-DD broadcast (from a DD broadcast), the receiver defaults to Surround Off mode. Am I missing something? I set the surround mode in the OSD to DPLII movie. Is this a defective unit or am I not setting it up correctly. Thank you in advance.
