if i set the output of the bd player to 1080p the colours and picture are completely distorted.
the amp is a yamaha rxv-1600, about 3 and a half years old. it's supposed to support hdmi 1.1 which does include 1080p. yamaha tech support were unable to give me a definitive answer either way, but it doesn't seem to work!
i haven't yet connected the bd player directly to the tv, which may seem an obvious thing to do, but it means removing the av amp from a built-in-wall cabinet to get to the cables, but i guess i will have to bite that bullet.
many thanks for all the comments so far!
