I have a JVC HD61FH97 that is 1080P. I have used a Toshiba HDXA2 HD DVD at 1080/24 with no issues and I get the incompatability error too. Pretty strange as my TV accepts pretty much everything, 480i/p, 720p/1080i/1080p......
Any suggestions? Using straight HDMI to the TV.
Wait to see if L6.13 fixes this issue.
