Ok, for awhile now my Marantz and HR34 have not played nicely, especially when it comes to pink screens. I recently went back and forth with running thru the Marantz with HDMI, or direct to the display with digi coax to the Marantz. What I've found is it works a lot better with HDMI to the display and coax to the Marantz. I also found, after noticing odd things with the picture, if I went into the Marantz menu and checked source rez, color space and pixel depth, vs output, there was an issue.
It should show (say for a 1080i channel on Directv)
1080i/60--1080i/60
ycbcr 444--ycbcr 444
8 bit--8bit
Well, whenever I jump to say a 720p channel, bascially something that requires a rez change, the Marantz info will go blank for input data and output. This was not always the case, because ive had the HR34 for awhile, but seems to be getting worse for me.
Long story short, if you have a Marantz or Denon and the HR34 is not playing nicely, then this is a suitable option for you. I know its not a Marantz internal issue because it plays fine with multiple Blu players, a Roku and an ATV.
