Image Jitter with older Game Consoles on Mits WD-65732

I suspect this topic has been covered, but this forum is so vast it could take days to find what I am looking for.

Two weeks ago I purchased a Mitsubishi WD-65732 (it was for the DVI mainly which they conveniently removed for later models....DRM anyone?)

Earlier this week I broke out my old NES, SNES, Sega Saturn and Sega Dreamcast among others to find that the ones I just mentioned have a compatibility issue (but for some reason my N64 works fine ) The image appears on the screen, but jitters up and down violently and if I try to look at it it gives me a good headache within 10 seconds. I called Mitsubishi and they say it is an incompatibility with a feature on the TV trying to up-convert every signal it receives to 1080p and with very low resolution inputs it can't compensate well enough to produce a stable image. This is a borderline deal-breaker for me as the TV was meant for gaming. On my NES I have used the old RF Adapter -> ANT as well as composite, SNES I have tried composite and S-Video and the Sega Saturn and Dreamcast only the composite as that is all I have. The Dreamcast has been hit or miss though - some games work fine and the boot up menu system works fine, but some games exhibit the same symptoms as I have described.

My question is if there is a box or any other solution that any one is aware of that will fix this issue. The images appear on the television just fine, only unstable and I can not believe that it would take much to alleviate the problem.

Thank you for any help.

My original XBOX is perfectly fine, which I have modded and can play NES and SNES on, but I admit there is something to be said for playing a game on its original hardware. The Saturn is my main concern as Guardian Heroes is one of my favorite games of all time. I have ordered an S-Video cable for it and I am hoping that helps, but I am not getting my hopes up.

I admit I was surprised the old RF Adapter hookup did not work - on either Channel 3 or 4 - It makes me quite sad since I am quite the 'retro gamer' - I was looking forward to playing some of my old games on my new and quite expensive TV

From what Mitsu told me the upscaling option can not be turned off. Sounds like they need to do a firmware update for that.

I got the S-Video cable for my Saturn and that fixed nothing - though it did make the image less "blocky". I did find that on my Dreamcast most of the games work totally fine, but the one I had tested with - Street Fighter III - Double Impact - is one of the extreme few that has a problem. And there is, of course, nothing I can do at this point for my NES or SNES.

In my opinion this problem is completely unacceptable as the images appear perfectly, only slightly unstable, and should be able to be fixed either through a firmware update or an external piece of equipment. Any tech "genies" on here have an answer for me?
