I have a problem with this player which is hooked up to a VSA-AX10i via an optical link. When playing a DVD's in DTS, no probs, the amp shows the DTS mode but when playing back Dolby Digital the amp stays in Pro-Logic II and won't let me change it. I tested an old Tosh SD510 which worked fine using the same connection and same discs, the Pioneer correctly (and automatically) changed to DD. I am assuming that the problem is with the RP82 and have gone through the settings which, to my limited knowledge, seem OK. So does anyone have any ideas of what is wrong? The other thing to point out is that the VSA-AX10i always shows a Pro-Logic on its screen for the DVD/LD Standard setting and then changes (or doesn't) when it detects the encoded signal. Is that normal?
