why watching DVD movie on HDTV not full screen?

Q. I have Samsung 46" HDTV 120hz. Every time I'm watching DVD movies, the picture 16:9 is so small (not full screen) When I zoom it, some of titles are cut. Please help.
I figured out by changing the setup on my panasonic upscalling dvd player. The viewing not full screen but good size of 16:9 widescreen.

A. First of all you must setup the DVD output format, this is done when no disc is in the player and using the menu buttons to navigate through the pages of menus.
Secondly you must realize that Hollywood doesn't make movies in 16x9 formats. They actually use many different size ratios dependent upon what feel they are going for. The TV manufacturers decided upon 16x9 because movies rarely ever go above this ratio for the vertical height. So TV broadcasters and made for tv movies will usually fill your screen if in HD, normally your movies will have a black bar on the top and bottom. The size of these bars are dependent upon the movie. Also make sure you are watching widescreen versions of the movie.

Why does our new plasma HDTV have a lower quality/grainy picture?
Q. We just got a 50" Samsung HPT5064 plasma HDTV and a lot of channels (non-HD) seem to have a grainy or low quality picture. Is there some setting we should change? Is this common for larger screens? We went from a 23" CRT TV to this so all of it is fairly new to me.
As someone asked, Comcast is our cable provider and they did provide us with an HD box.

Also, we're sitting probably around 10-12 feet from the television.

A. SD TV does not look good on an HDTV. On my 40", I have to sit about 8" back for it to look good, and my set was well rated for SD display. How good or bad it looks depends on the input signal's quality. A 50" widescreen has a picture height equivalent to a 41" standard TV. When you blow-up analog TV that was never designed for displays that large, right away you have a problem. On top of that, in order to be displayed on an HDTV, the signal has to be deinterlaced and up-scaled to the native resolution of the set. This processing introduces artifacts. Non-up-converted DVDs should look pretty good. That;'s as good as you can get from SD material. If from about 10", your picture isn't acceptable, then you may want to look for a set that's better rated for SD.
