you will have to get one of the LCDs (or the couple of Plasmas and RPTVs) that have 120hz processing.
Samsung, Sony, and Sharp, all make them.
No component does this currently though.
I recently bought a 52" Sharp Aquos LC-52D82U and I couldn't figure out how to make it show movies like the Samsung 5271 on display at Best Buy. I later found out that the Samsung employs anti-judder technology that I believe my TV lacks. I don't feel like returning the TV since it is so big and would require alot of messy financial restructuring on account I bought it with a new Circuit City account and had a bundled Blu Ray player. I was wondering if there is such thing as a device out there that I can buy and pass the video signal through that would provide me with Anti-judder. Anyone know of anything like that or perhaps how I can achieve the same picture quality short of acquiring a new TV?
