Sounds like I don't have to worry about the RGB shift.
DMI sounds to me like some sort of progressive scan imitation. Have you experienced the flickering when it's turned on using NTSC material?
I checked the set in the shop, it was using an RF signal (daisychained across the entire shop as usual...), and I didn't notice any pixellation. Picture wasn't perfect, but that can't be expected from such a signal. Compared to other sets, I wasn't too impressed on first sight, but on closer examination the set isn't as 'exciting' with colors, but it does look a bit more natural. I'll try to get a demo of it using my own DVD player in a couple of weeks. I'll definitely need to check it with a football match, since this seems to be The Test for 100hz TVs (although my parents' 4:3 100hz Sony copes very well with it).
I did notice that the back of the panel is a bit flimsy, and the casework isn't up to the standards of the more expensive Loewes. However, it's not that much worse than comparable Philipses, Sonys or JVCs. The design is very minimalistic; I think I'll get used to it as long as it performs the way I want it to
