Xenonman et all.

I have to jump in here and comment on the "soap opera effect " that you refer to. It is mostly caused by either noise reduction circuitry or motion smoothing which are in the set up menu of the TV. Scaling usually does not cause this issue

Recently one of my friends set up a new 52 inch Samsung and all of that cicuitry was active as the "default" setting. All TV shows and movies all tended to look like high quality" live" video. What a horror show!. After we bypassed all of it he was stunned at the improvement. With all of that enhancement circuitry turned off movies and TV series looked like what they were supposed to look like- film

So, for anyone that is having this issue, it can be easily addressed by just turning off most of that stuff in the set-up menu.
