I purchased a combo DVD and BluRay edition of Avatar this evening and was looking forward to seeing the BluRay version on my Oppo BDP-83. However, the BluRay would not play. It showed 15 seconds of the 20th Century intro and then went blank. My Oppo just said "Top Menu" on its screen and pressing a variety of remote buttons did not make a change. Anyone else have this problem? My Oppo was one of the first out so there may be a firmware update available. Any suggestions?
