Question With the new formats from DOLBY and DTS designed for 6.1 surround and todays AVR'S with 6.1 And 7.1 setup capablities.. Is it required for DVD's to be encoded with the new formats or does the AVR and DVD players assign a 6th or 7th channel to carry the signal back to your backsurround speaker.. I want to add an additional QS4 for 6.1 set up.. But would wait to buy a back surround if DVD's have to be encode with the newer formats. I havent seen any DVD menu audio setup with the newer formats?
