1080P video via HDMI generates awful interference
Equipment: Onkyo TX-SR705. Panasonic DMP-BD30. Panasonic TC-P50S1 plasma (Just purchased 1 week ago). For 1 year the receiver and the Blu Ray were connected to a Panasonic TH-50PM50U 1080i via HDMI. HD audio & 1080i video ran perfectively. When I purchased the 1080P and connected exactly the same manner all HD audio sources are perfect but the 1080P video has awful interference. The only way I have been able to eliminate the interference is to connect video directly to the plasma and by pass the Onkyo. Onkyo support had me test all HDMI inputs with satellite HD DVR 1080i). No problem. Minute I attempt 1080P video the awful interference starts. Please help!

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.
