I think there's a way to get the 1050 to extract rear center channel information from a DTS ES (NOT DTS 6.1 Discrete) using an outboard decoder and feeding the 5.1 output in through the 1050's 5.1 input. At least that's what the review in Widescreen Review said. Probably not worth the effort, though. The new preamp/processors are supposed to decode DTS ES and DTS 6.1 Discrete, and (using Outlaws proprietary 6.1 format) Surround EX soundtracks.
