This is my first report. For those concerned about the issue of HDMI to DVI conversion, I had no problem outputting the XA2 via HDMI at both 1080i and 1080p.
On the video side, the HDMI output of the XA2 feeds the HDMI input of a Vantage-HD scaler (Realta chip). The scaler outputs to a HD10K, incredibly calibrated by Mr. Phelps projected on to a 100" ST 130 screen. I used Superman Returns HD-DVD because that is the only disc I have besides Polar Express. Many have said that Superman Returns is not the best HD transfer. Since this is the only HD-DVD I have seen thus far (albeit briefly) in my theater, I have no basis of comparison. But the output at both 1080i and 1080p was very impressive to my eyes. I certainly looked better than most of what I have seen on HD cable (HBO-HD, Showtime-HD, etc.). I briefly watched it, going through scenes to view black level, detail, color, etc. If this is a mediocre transfer, I can't wait to get some good ones. I have no opinion yet as to whether 1080i or 1080p looks better. I will need more time and viewing. I suspect my Vantage will do a better job than the Reon in the XA2, but that is just conjecture at this point.
On the audio side, I am outputting via digital coax and 5.1 analog to a Lexicon MC-12B 4eq. I also listened to the digital and analog output of Superman Returns, switching back and forth, and both sounded very pleasant to me. Again, this was brief and I will try to do more thorough evaluation as I get more HD discs and, more difficult to come by, some free time.
I realize that the Vantage scaler may be the reason why I am having no trouble with HDMI to DVI, and I have not tried a direct link from the XA2 to the HD10K, but I wanted to post my success with the XA2 at these resolutions in my setup. YMMV. I hope not.
BTW, my kids, who are used to seeing movies in my theater came in during my limited viewing. Suffice it to say, they were impressed and we now have a date to watch the entire movie tomorrow.
Finally, so far, the XA2 is wonderful and has met or exceeded my expectations. This is very exciting.
PS. I don't own BR yet, so don't ask!!! Please stay on topic
