I'm not sure where this question should be posed, and this is my best guess, so here it is. Last night, we finally got around to watching "Terminator 3". It gets my vote for "MOST INTENSIVE USE OF DD!" But I noticed the DTS logo during the ending credits. There were no sound set-up options in the menu. My receiver (Yamaha HTR-5630) auto-detects 99+% of the disks and automatically switches to the correct sound format. With T3, and others bearing the DTS logo, it switches. Just not always to DTS. It seems to be hit or miss. So my question is: Have others had similar experiences? Is it something being missed by the receiver or something missing from the DVD?
