Getting 2.0 Surround Sound - DVDfile.com forum for DVD, Blu-Ray, and HD-DVD

Recently updated my sound system, and am at a loss at getting surround sound off a few disks that are labeled "2.0 Surround Sound". Disks include: Last Emperor, X-files Season #1; Army of Darkness Directors Cut; Blair Witch Project, Commitments and Life of Brian.

Have Panasonic DVD-A110, Technics SA-AX720 Reciever, Technics SH-AC500D Sound Processor. No "Pro-Logic" symbol is picked up at the recievers and no sound from center or surrounds.

Other Surround Disks work fine. Any leads would be appreciated.

The SH-AC500D has a problem of sorts... Sometimes it doesn't go to Pro-Logic. I imagine that this is a problem with a flag embedded in the audio stream (or more likely a lack of a flag on some titles) that doesn't switch the DD/DTS decoder to Pro-logic mode... therefor it thinks that it is decoding 5.1 channels still, but there is only L and R channels.

What I would suggest is for those titles to switch out of the 6-channel direct mode on the receiver and let the receiver do the Pro-Logic decoding.

Commentary tracks will often do this too.

TaDah! That indeed was the problem! Now I have to re-rent the Commitments and watch all X-files DVDs again to get the sourround sound.

Thanks.
