Was watching LOTR earlier today and this isn't really a problem...just curiosity. I have an older Sony DVD Player -- DVP-NC600 which has the regular DTS. My receiver, Pioneer Elite 45tx, has DTS ES. I know DTS ES is for the extra rear channels. However...I am talking about sound in general (and not necessarily DTS) Question is this. Does the DVD player have any effect on the sound quality or is this handle solely on the receiver? Would I benefit in upgrading the DVD player for sound quality purposes? Guess I am just wondering which is more important...the sound conversions on the DVD player...or the receiver. Hope I didn't confuse anyone.
