Thanks dfp. I've been impressed with the reviews of the LG LW5600, the problem is that the RCA I purchased has very few reviews (the few it has are from others who purchased and they are positive), so it's hard for me to tell if I'd have the same issues with the LG, as I do with the RCA. My hunch tells me the LG would be better, since I don't see the judder on our 32" LG LED or our 50" Hitachi LCD Rear Projection. However, if it's something due to the source material and it only gets picked up by the 46" LED, then I could still have the issue. What I may do, is pick up the LG and if it isn't any better, return it. If it is, return the RCA. It's too bad with all the technology we have, that this would be an issue, but sometimes for every two steps forward, there is one step back, I suppose.
