"I have noticed when watching a movie in 1080i it will looking fine and then every once in awhile produce a twitch or flash on the screen. I have tried different movies to rule that out as a potential problem and all have done same thing. I think there is slight sync problem here as when running in 720p I do not get this same result and the image remains stable. I like 720p but the image seems to look and fit the screen better in 1080i. It may also be a copy protection encoding error, I will check out some of my burnt archive movies to test this theory out. I will be investigating the cables tonight and also looking for a possible setting in the Oppo or the projector to fix this problem. Not sure which it is or even if it may be my long run of cable, but 720p is fine so not convinced it's the cables fault. I will also call Oppo and Optoma tomorrow to get their take on it."
It's the Oppo and the cable length. I had problems with the Oppo and 1080i with different projectors. The Oppo wasn't alone add the Bravo D2 also. To fix the dropouts and sparklies I use a shorter location and went to 15' digital cables. The Toshiba HDA1 was trouble at first even with a 6' cable but the scaler fixed it even using a 25' cable.
If we've learned anything, cables and cable lengths devices and receivers in the digital age can give you allot of signal level problems. When I went to the close up route I thought all my problems were solved, until the Toshiba. If I don't buy the Scaler I'll be dumping the HDA1. The Engineer's looking at the troubles with the HDA1 going direct to the HD7100 maybe he can find a fix.
I'm glad a few more of you are getting a good look at the HD7100. It's really something to look at. I wanted to own this thing immediately, figured I could hold off on 1080p with a image this good. The sharpness the lens adds for me could make up for the lost resolution, at least that's what I tell myself.
