Hi, I am new to this forum. Currently I am trying to make a home theatre with wireless rear surround speaker. I am gonna use a receiver with decoder built-in and is 100watt/ch. For rear speaker he said there is a new product coming out which is a wireless transmitter that getting signal from DVD player surround output then it will transmit to a receiver at back that supply 50watt power and have 2 thin speaker wire connect to 2 rear speakers. In order to do that I must have a decoder built-in DVD PLAYER because the receiver does not have a separate RCA output for the transmitter. My question is, how good are those wireless thing and is that true that the majority DVD players will have decoder built-in or is a trend that more and more decoder will be built-in in future?
