Unfortunately, and oddly enough, 1080P isn't 1080P. 1080P is measured for a still (static) image. For video, which is what a TV is for, there is what is called "Motion Image Resolution" (MIR) or Moving Picture Resolution. Turns out, for video, most TV's only use 300-900 lines of resolution. Most lower model plasma's (all non-panasonic's currently) use 600-800 MIR, 60hz LCD's use about 380 MIR, 120hz use about 600 MIR and 240hz use about 900 MIR. Panasonic S/G/V/Z Series and Pioneer's are the only TV's to currently use all 1080P for their MIR. In essence, only those Panasonic Series and Pioneer plasmas are TRUE 1080P.
120hz and 240hz help with the MIR, but the way it works causes image shutter because it does it by "guessing". The 120/240hz processor known as ME/MC (motion estimation/motion compensation) guesses what the image is going to do on the next frame. Since it's a guess, often times it is wrong which is what creates the image degradation and creates the "video/soap opera effect" of the image (where it seems the foreground is floating over the background). While this works ok for normal TV viewing, it severly degrades the image quality of Bluray because Bluray contains the correct information so the ME/MC processor guesses wrong very often. Plasmas don't have ME/MC circuits so they don't suffer from this issue.
Heres some links to some more information. Some of the links include videos which show how a plasma correctly displays motion vs. a lcd.
