DVR playback in postage stamp format

The first thing I changed was the "zoom" setting in the box setup under Device settings/video device. When I first noticed the problem, the display for DVR playback had only top and bottom black bars and was compressed vertically. I discovered that the device "zoom" setting was set to "fill" (I think that's what it was called) so I changed it to "none". That fixed the aspect problem and gave me the postage stamp output mentioned in the original post. It's funny that some channels playing pre-HDTV content are able to play back DVR recordings just fine. I'll do a little more research to narrow down which channels do and which don't have this anomaly. As far as I can tell, all channels that are already in HD (16:9) format play DVR recordings just as they appear in the live broadcast. It's only some channels that play DVR recordings in reduced size and don't "zoom" them to fill the screen as they did a couple of weeks ago. Did something change in the box software?

XG2v2-P is the cable box model. I don't know what kind of DVR it has. When I referred to "postage stamp" format in the posts I mean it looks like the output from an SD station.

For a TV show to be in 16:9 Widescreen format, older programs have to be remastered to make this happen. Converting a 4:3 film to 16:9 is not something I personally enjoy since it would crop a portion of the frame. Everything is working as it should, Gunsmoke is airing in its standard 4:3 format. You could stretch the frame with your TV settings, but I would not recommend that either as it would make the footage appear unnatural.  But as to address the initial concern, this working normally, the program you are looking to enjoy is in 4:3 format.
