I just purchased a Yamaha VX 663 and I am running it with a Pannasonic DM-30 BD. When it decodes DTS MA it only brings up 5.1 channels. I tried it with Shootem up and that movie is in 7.1 DTS-MA. Also, I can't get it to decode anything in True HD. I have tried every setup between the Panny and the Yamaha and nothing gives. Does anyone have this setup by any chance ? Any help is appreciated :)

Are you sure you selected the DTS-MA and TrueHD audio options on the disk?

I can do PCM just fine. There is still a question as to this issue. Please call Yamaha.

Have Fun!

Yes I selected those options on the discs !

Do you have your BD-30 set to bitstream everything and secondary audio to off?
