Spiky Thanks for your feedback. I know of Dolby Digital EX and DTS ES. Both dolby and dts have a list of movies on their web site that are in 6.1 but most of the ones I have checked are not, X Men, Pitch Black, Bone Colector, The Ring, A I, and both Star Wars movies for example. Im trying to get a list of DVDs that are in 6.1 that will send a signal to the back center speaker with out having to use the enhanced mode on my av reciever, is all that does is take a blend of the back R and L speakers and send it to the center which sounds ok but I would like more movies that have a direct signal to that speaker. Thanks for any help anyone can give me.---Cope---
