I am contemplating the purchase of this unit and need a couple of simple questions answered. 1. Does this unit decode dd-ex material? I have read that it does dts es, so it probably does dd ex also. Is this the same as THX surrond ex? 2. I have an older tv that only has (1) s-video input. If I hook up my dvd player, and satellite receiver to the receiver using s-video, will I only have to have one connection from the receiver to the tv using s-video? How is this achieved? Will it degrade my picture by running it through the receiver instead of directly to the tv.
