I have a Yamaha HTR-5560 A/V receiver. I have all 6 speakers set up in the way recommended. The Lord of the Rings DVD that I got for Christmas will not play in the 6.1 format. It says "6.1 ES Surround" in the setup, but the list here: http://www.hometheaterforum.com/htfo...ighlight=dtses says it's both ES and EX. My questions are: Can EX (matrixed) do ES (discrete)? Do I have somthing set wrong on my receiver? Will I only be able to listen to 5.1? Is the list wrong? What does "ES-Compatible" (as it says on the Yamaha website) mean?
