Can the latest DCX3200 streach the picture of non HD channels to fill up the tv screen (16:9)?
Service menu on the previous version (Old guide style) had a 4:3 overide setting. New box doesn't allow you to change this preset.
Yep, this can still be done. For newer HD Guide models this setting is found under Video Setup > Aspect Ratio > set to Stretch, as shown in High Definition Guide - Video Setup.
Since this box will only display HD only resolutions (16:9), there is no 4:3 override setting for the lower SD channels. You can adjust the aspect ratio as mentioned by Jeff above on the video setup but that will stretch the image so you may prefer to keep it as is. Alternatively you can adjust this aspect ratio via your TV as well.
