Ok, here is my setup. I have my PS2 connected to my B&K AVR202 receiver with the Monster optical cable. But here is the problem. I switched the Dolby Digital to "On" in Metal Gear Solid 2 for the cut scenes. Sounds great, until the cut scene stops and you start playing, or using the Codec. Then there is no sound. For some reason, the receiver won't default back to normal stereo when the Dolby digital signal is passed. To get sound back, I have to shut off my PS2 and turn it back on. I also have to do this if I play SSX Tricky in DTS and then want to put in another game. Anyone have any idea what the problem might be?
