Neyrinck DD2 - AC3 5.1 encode played back in 7.1 system question.

[jgbsound]

Hello All,

 

I am attempting to encode a 5.1 source track into a 5.1 AC3 surround matrix using Neyrinck's Dolby Digital 2 plugin in Protools.  I am creating a blu-ray for festival submissions.

I seem to have everything in the right place (I've tested it in Dolby Digital 2's preview and all the correct channels are playing back in the assigned channel). 

However, when I take it over to my home theater system which is 7.1,  I've noticed that the surround channels (Ls/Rs) are playing out of the mid-room surrounds and NOT the back speakers as would just a 5.1 configuration.

 

When I play a consumer surround disk, they seem to play back properly, just my disk seems to be wonky.

 

I tried re-exporting with the EX bit extension but the disk still plays the same way.

 

My question is this:  Is there something in the encoding that I need to configure that might affect the distribution of the encoded channels?  How do I get the disk to map the Ls/Rs to  the rear channels?

 

Thanks for any guidance you can give me!

Hey John, I know your query was AGES ago, but I'm in the same boat, have the plug-in and everything and I haven't been able to get it to work yet.  Did you ever solve this riddle?!

 

Cheers.
