SOURCE: 1080P video via HDMI generates awful interference

Your Plasma's native resolution is 720P. Go into the Blu Ray's output setup. you can choose 480p 480i 720p 1080i and 1080p. Set it for 720p that should clear up the issue.You may have to run Component directly to the TV since you only have 1 HDMI input and you can run Digital coax or optical to your AV receiver for audio. On a 50" TV the difference between 720p and 1080p using "GOOD" cables cannot be seen by the human eye. Above 50, yes it is noticeable.
Hope this helps.

For me, it was the Monitor Out setting that had defaulted back to Component. I remembered to change the individual inputs to HDMI - but had forgotten to set the Monitor Out to be HDMI.
