Thanks for a very clear point-by-point comparison.
I have a PS3 for DVD playback (as well as games) - and I may have a problem with MoviePlus (Samsung "Movie Plus" causing artifacts - AVForums.com)
Also I have very sensitive eyes and I think the 100hz might help with this. I think with me the viewership is 90% TV (parents) and 10% games+DVD (me).
So, I'm hoping I'm right in thinking the 800 series is the better choice.
well since u have a ps3 and are going to use it for gaming too u should consider a sony since it has the least input lag of less then 10ms the panasonic is at a quite high 30ms and the samsung are dead last .
