I would say 100%, Tom. If your receiver is showing the Pro Logic that is because it is picking up the surround signal that is encoded, that is the way it used to be done way back before we got DD Surround 4.0 or DD Surround 5.1 and above.

Skip


Well, if it's ProLogic II, then it could very well be converting a stereo signal to 5.1 surround. The images of the AV receiver's display seem to support this.

btw. "Dolby Prologic (II)"-Receiver can not convert Stereo into 5.1... it's not magic or witchery ;-)
if there are no matrixed channels in the 2.0 sound, then you can't create them by nothing...

Dolby Surround has 2 discrete channels, so 2.0 is correct.

We track by matrixed channels.

maybe. but the rest of the world does not ;-) (See tkinnen's picture from the audio-menu... ;-) )

still "2.0 surround" is the best describtion for a "Dolby Surround" (dts Stereo, etc...) soundtrack, because 4.0 is not correct as well. (because there are no 4 discrete channels)

so back to the start-posting from tkinnen.

If you can hear (usefull) sounds through your rear- and center-speakers it's Stereo-surround (2.0 surround) no matter what the flags say

If you only here sound thru the center.. it's 2.0 Mono (so no real stereo)

if you only here thru left and right speakers (especially no rears) than it's just (real) stereo (2.0)

Does anybody have a link to an AV-file with DD2.0 and Surround flag?


I don't know how it's flagged but Billy Wilders "The Seven Year Itch" is a real 3-channel soundtrack (left, center, right) in original (no rear-lanes).

Then it's of no use.

I'm after the flag, like my earless machine.

normally the majority of DVDs with a "Dolby Surround"-sound track are 2.0 + surround-flag (so the flag is a very good indicator, but no proof or guarantee)

Yeah, definitely not a guarantee. I've found quite a few DVD's that are "Mono", but decode with a "Surround" flag in certain programs. The last one was Mr. Mom from MGM. Anchor Bay did it quite often on their older releases.

you're right Corey,

so:

1.) don't always believe what's written on cover or disc or what the your pc-prog  told you

2.) believe in your ears and brain
