In the Set-Up menu on the Yamaha make sure you tell it that you are only using one surround back speaker. That will create only one channel when the receiver is using its DSP to derive the surround back information. Real 6.1 movies only have one additional channel. To the best of my knowledge there is no such thing as a 7.1 movie, only 5.1 and 6.1 for DD and DTS with or without THX. The receivers can artificially make separate surr back left and right channels though ( 5 channel stereo becomes 7 channel stereo with 2 ch sources ), but only when the source is 5.1 or less channels. Specifiy only one rear speaker and the DSP will only make one rear channel !
The Yamaha is a good receiver, but I doubt it would be an upgrade. It is too similiar in relative quality. Does the Yamaha have component video up conversion from composite and S-video that the Marantz does not.?? IF so and you wanted to send a VCR of SD sat receiver to a single component input on an HDTV, than that may be useful, otherwise I probably would not bother.
