    I have had the Samsung p5063w 50" DLP for a week now. DVD's are amazing, almost HD quality with no issues. The problem is HD Broadcasts. I have Comcast HD, component connect, and when watching in 1080i, when action gets fast or a quick switch between scenes, heavy pixelization for a split second. When watching nature shows, no problem, but sports or movie channels in HD, a big problem all the time.

    Is this normal for DLP???? I am doing something wrong??? It happens all the time and I think unwatchable.

    Rainbow effect I expect on DLP but pixelization is usually from the HD tuner not the DLP set. I have D* (Directv) with OTA HD for my locals and this only happens on the OTA stations never on the D* HD channels and attribute this to the local affilliate and signal strength not my TV set.

    This is a problem of "Live" MPEG encoding and has nothing to do with your set or any transmission problems. The problem is the HD max bandwidth and an overflow of the MPEG encoder which can't keep up and breaks into it's cos squares. This is worst in fast action sequences such as basketball, etc. With DVDs and recorded programming, there are usually several passes thru a compression machine and it's a variable adjustment as to the compression and the number of "I" frames.

    Welcome to the world of digital television. Every improvement in technology brings with it new artifacts and it takes a little time to develop the jargon to talk about the new problems.

    Such is progress and tech talk.
