I recently got this DVD, widescreen, with Dolby Digital 5.1 and DTS soundtrack (says so on the back cover). In the Languages menu I can select either DTS or DD. I picked DD since my receiver does not decode DTS. But all I'm getting is Dolby Pro Logic, as shown on my receiver's read-out. What's going on? I've had no problem with other DVDs' 5.1 soundtrack. Anybody has this DVD can check for me? Thanks!
