I have a Samsung SIR-TS360 connected to an HK AVR-225 via digital coax for the audio connection. When the Samsung outputs "bitstream", the HK will play in dolby digital 5.1 if the program is DD but if its just analog, it will jump to 2 channel stereo. I'd prefer it to jump to Pro Logic II movie. Does anyone know if there is a way to force the AVR-225 to go into Pro Logic II (or even Logic 7) when it receives an "analog" signal? Lately I've been leaving the Samsung's audio out to "PCM" so its Pro Logic II all the time to avoid having to toggle back while channel surfing. Any advice would be greatly appreciated.
