if the video on a wide screen shows black borders at all 4 sides

[Benarty]

Sometimes DVBViewer is not able to stretch the video to full screen or in case of weird formats, only black bars at top and bottom.

 

If the computer stretches the video and not the TV, this means that DVBViewer has a problem to auto detect the video format.

You can test it by changing auto to for instance 16:9 and then you will have wide screen video.

 

This could be a DVBViewer fault, cause, the video format is 720x576 and even then the video format is not recognized so shows letterbox format.

 

I found this as soon when the computer was stretching the video and not the TV.

The TV itself has no problem to stretch these problem channels.

the setting "auto" will show the original format. This can be 16:9 or 4:3. This will result in black bars in 4:3 mode left and right, in 4:3 letterbox transmission left right and top bottom and in 16:9 transmissions that are cinemascope (wider than 16:9) top and bottom. This is correct and how it should work because this way there is neither cropping nor stretching involded. If you want all content to be strecthed to 16:9 then choose 16:9. But this will result in incorrect proportions for 4:3 and 4:3 letterbox transmissions. There are tv that zoom and crop automatically to remove black bars in 4:3 letterbox (which you can to in DVBViewer manually) or the tv zooms in on cinemascope transmission which will reuslt in lost picture on left right and less quality.

 

So what exactly do you want DVBViewer to do?

argh, I enabled resizing on the TV again.

I guess better results then the computer.

A possible solution :

 

Stretch anyway but keep ratio, in case of 4:3 this means no borders under and above but only left and right on a 16:9 but smaller then the current 4:3 view on a 16:9

Strecthing on the TV looses active parts of the video on the horizontal side.
