Dbld I didn't know that . Thanks for the headsup. My plan is to use the Logic 7 in the Lexicon MC-4 Digital Processor to create the multichannels from 2 channels on the DVD-A, and SACD discs. I've ben told that the MC-4 does a better job in most cases than what is on the original disc. For example, some multichannel discs have musical instruments coming out the rear speakers; whereas the MC-4 uses the back speakers for ambience only. This is the correct procedure in my opinion.
