I just upgraded my receiver this week to a Ymamha RX-V1300 and had my first taste (finally) of DTS sound last night. I do have a question about DTS ES and 6.1 Discrete (and I guess really DD ES as well). My dvd player is a 2 year old Pioneer DV-525 with on-board DD decoding and "DTS out". I have it connected via toslink. Now, these matrixed and 6.1 discrete formats we not around when I bought this. Do the signals that carry basic DTS vs. DTS 6.1 different? Will my "DTS out" player get the newer 6.1 signal to my receiver? Thanks for the help. I really have no idea about this since I haven't had to worry about it until now.
