Im getting a new Processor, it's a Sunfire TGP-5 it will process all the leading movie sound formats like Dolby prologic II, 5.1 Dolby digital, 7.1, DTS, DTS EX, DTS neo 6 ect. My question is WHY??? what Im leading up to is that almost all the movies on DVD are in 5.1 Dolby digital, and there are some older ones in DTS, so what good is having a processor that will decode all the formats, when the only one thats really available is 5.1 dolby digital? I once read that all the new movies have all the newer formats in them, but 5.1 Dolby digital is the main one. I have a feeling that Im all wrong on this, and if so PLEASE explain it to me.
