I've also done a side-by-side this time with an Oppo971 on an ISF'ed 60" A2000 SXRD. The A1 does a better job of upconverting IMO. I was going to put the 971 on EBay but I just gave it away to my kid brother who just got his first HDTV. He likes it a lot. Of all the players I've tried the XA2 is by far the best because of the Reon chip. On the 360 add-on: error5 and the avsforum FAQ are correct. I've seen a friend playing a standard DVD upconverted to 1080p using VGA on a Samsung DLP.
