Ok folks - just finished setting up my system with my brand spankin' new 1019. It took me about 3 hours, but I took my time doing this.
Setup was easy. My previous AVR (Sony STR-DG600) was a multi-channel AVR, so my cable count has gone down quite a bit. I got rid of one multi-channel set of RCA cables, two optical cables. HDMI all the way, connections from a BD player (OPPO 83), an HD-DVD player (HD-A35) and a Verizon FIOS motorola box. I added one HDMI cable, from the AVR to the HDTV.
My main delay was not seeing the setup display, which was getting me ticked, I finally checked the connections and sure enough, did not connect the TV to the output
Ran the MCACC and it set things up perfectly. The sound was excellent (and definitely improved) on HD DVD on several sources - Batman Returns, That's Entertainment, I Robot (SD) - then the FIOS was again excellent on 2 and surround channel. I used the tuner for regular radio music, haven't tried CD yet, but am expecting good things.
Loving this box. I shut down the KURO link, set up the inputs (renamed a couple) and at the end of all, re programmed the Harmony 670. My wife came home, used the remote and got the exact same results (and commented on the sound).
Will investigate more, but basically moving into enjoying all the media now.
