Only because far too often we read posts about how some little setting can't be tweaked or some minor (or major) problem is occurring with the D2, I would like to report that I am completely happy with my D2. For those having trouble, stick with it because it is worth it.
I have had some minor issues, but all were resolvable (HTPC issue solve by Geffen DVI detective) or frankly not important. The D2 sits on the cutting edge, but we get cutting edge performance out of it. For all the "gut wrenching" over the decision to go with the D2 vs. a separate video processor and a standard pre-amp, I realized it was all for naught. The D2 is fantastic, was the right decision, and would recommend it to anyone who is evenly slightly technologically inclined. If you are the kind of person that will fiddle with settings and even enjoys doing your own setup work this is the box for you (and if you are reading posts here, then it probably is you)
If all you want a press the on button on a TV and press the channel up/down and simply watch tv, then I'd tell you to a pass. But then again, if that is all you want, then you probably aren't reading posts to this forum.
At this point, my only concern is that I'm NOT knowledgable enough to be getting the most out of the unit. I have not tweaked the sound beyond measuring distances to my seating location. I don't know if I have speaker sizes set right (I'm sure I don't), have subwoofer settings right, etc... Then there is the video. There are so many ways to tweak the picture I'm just learning what I like to see. I haven't optimized my color settings, and the noise and motion processing make me feel like a novice (which I am).
However, this means that I have many more months of enjoying the hobby of playing with the D2 before I get it all "perfect", when of course all I will have left is watching TV and movies on an awesome screen with a fantastic picture and realistic sound.
Now if I had just waited and not gotten the Panny 65" since it can't do 24fps life would be perfect.....
