Hi

How can I change the x:y aspect ratio in progdvb.
If I change the size of display windows, it keeps the ratio (4:3 or 16:9) filling with black zones the windows (and I want a distorted image displayed)

I've changed the settings->audio and video->directshow>letter box mode
but that is not what i want.

Thanks

You can cut the borders also in ´settings->audio and video->directshow´ ....nothing more do to in progdvb....maybe change of codec or video card settings (driver) will help

What happens in full screen mode? Exactly the same or anything different?

BTW, not wanting letterbox mode means to have to set letterbox=none.
Also possible, you may have to check the codec properties.
Some codecs do follow ProgDVB's requests, others don't.

And perhaps even the renderer selected may matter.

And of course there's nothing to be done, if 16:9 or other widescreen material is transmitted letterboxed into 4:3. Then the whole DVB system won't know about original resolution and scaling.

Another source of trouble is windows, almost always runs into trouble, if real screen aspect ratio is not identical with pixel aspect ratio. Better use a resolution that really suits your screen. Measure and calculate, if not sure.
On CRTs, most, but not all, from 15" to 19" really are 5:4.
A screen reso of 1280x1024 also would be 5:4, but a 4:3 screen would need 1280x960 instead, when using stupid Windows square pixel calculation...
A CRT of 5:4 is easier and cheaper to make, a TFT maker would get more panels out of a mother glass pane on 5:4. that'sa why both of them use 5:4 instead of 4:3, for medium size screens.
Same goes for TV screens of both types.
And für wide screens, that normally are 16:10 or 15:9, instead of true 16:9.
Just a matter of savings...
Sixty to around fifty years ago, the first color picture tubes were completely round and extremely long necked, deflection angle around 60 to 70 degrees. But even then good enough for all the early adopters...

A bit complicated, and in many cases there's definitely no perfect solution for all applications at a time, both in Window mode and full screen.
