A few months ago I had my 989 upgraded with DTS EX and Dolby ProLogic II. Everything seemed to work fine but here lately whenever I watch something in ProLgic II, I get center channel (dialogue) information bleeding over into the rears from time to time. It doesn't happen consistently, purely random. At first I thought maybe it was a software issue but now it seems to be a problem with anything that's 2.0 surround. I no longer have standard ProLogic anymore once I had the amp upgraded. ProLogic II Music mode seems to be working ok, at least the last time I used it. Anyone else have a problem like this?
