Any Comcast Tech's here?.....

I have a HD DVR box (DCH3416) and SD channels don't fill the screen. How do I fix this problem? I tried everything.. Whats the point of having a 50" Plasma when the Sd channels are only half the screen?
Thanks for any help!

Its not the box.... Try and change the aspect ratio on your TV. In order to get the perfect HD picture on mine the sd channels are also smaller... I dont mind tho because 99% of what we watch is in HD anyways.

If you want your SD 4:3 pics to fill the wide screen, you have to go into the settings on the box. You can choose how you want the SD pics to fill the screen...stretch, zoom, etc.

How do I get into the box settings? I tried all the aspect 4:3, 16:9 and wide fit is too large and cuts off part of the picture....
Thank you

I'm guessing even if you can change the settings in the box you are not going to have the picture you are wanting..... By stretching, zooming, etc... All these things will fill the screen but at the same time give you a even worse picture. Your best SD picture will not fill the screen.

4:3 and 16:9 aspect ratio's are obviously different. Imagine a photo print taken with a 4"x5" film camera, it will enlarge directly to 8"x10", twice the size. It can be enlarged again at 16x20" also, notice the image stays in proportion Now take a 4x6 print and enlarge it to 8x10... you end up with a print that is effectively 8x12... it does not fit the paper directly, you lose part of the image by cropping. The same thing on television. You cannot take a 4:3 picture and magically make it into a 16:9 without losing parts of the picture, or compressing the image to fit, resulting in short and fat people
Old televisions are based on an image that is 4 units wide by 3 units high, the units can be inches, of feet if you had a large enough display. Now try to make that picture fit into a 16 wide by 9 unit high frame.. good luck, something from the image is dropped or compressed. Can't put 5 pounds of caca in a 2 pound jar...

No, no, no. YOu don't do anything in the box. The settings that need to be changed are in your TV. Somewhere in the TV's menu will be settings for the screen. You can then alter the 4:3 aspect ratio to something like "full".
I keep Auto Wide set to On
also set Wide Mode to Full
and 4:3 Default to Full

Check out your TV screen settings.

Keep in mind however, once get the SD channels to "fill" your screen they're going to be stretched horizontally.
