Denon 2930ci Looks Like Crap on 1080P LCD?

Greetings Agoners.A little over a week ago I jumped on a brand new Toshiba 42" 1080P LCD for my small home theater system, moving up from an older 37" Philips LCD.For the first week I was sourced by a Denon DVD 1920 set at 720P output & the pic was STUNNING.Of course being the typical A/V Phile I figured a new 1080P upconverting DVD/P would really put my tv over the top.Well yesterday I drove 250 miles round trip to pick up a brand new Denon DVD 2930ci.Got home & spent the next 1/2 hour getting the old deck out & the new deck in.Set up all the video parameters & threw in the first disc.NO!!!!!The pic was crap.Processing lines could be seen & it was totaly soft.In went disc after disc with the same result.I went through EVERY video parameter,trying all levels of output,1080P,1080i,720P & even 480/576P&i.Nothing made a bit of difference except to get even worse.W.T.F.?I put the old deck back in along side the new one & the pic was back to it's awesome status.I really want to keep the 2930ci because it's audio output is fantastic & a definite step up from the 1920 but don't think I can justify keeping the $850.00 machine just for an audio disc player.Video cable is an Audioquest HDMi3(top of the A/Q line)& the deck is set up on VibraPods & pluged into a digitally isolated recep on my Pure AV power conditioner.I even tried plugging sraight into the wall but that didn't help either.Any suggestions on what the problem may be & how to fix it?Thanks in advance for any help provided.
