mpg playback - aspect ratio & Full screen

Hi, I'm new here
Playback of movie files seems to work well with most file types except for Digital TV Broadcast captures.
The resolution of these mpg files does not match the aspect ratio that they are supposed to be played with. ie the people are squished from the sides and look tall and skinny. I don't know much about how they are encoded, but I know that players like zoom player and media player classic use the aspect ratio to produce the correct aspect ratio.
Is is possible to force a video playback to be full screen? The closest I can get is a big white boarder around the edges of a video. It would be nice to have the video stretched so there is no border.

Do you have a little sample?

I have produced a 1/10sec sample (~350KB).
You can download it from:

I have to say that your player decodes these files very quickly (much faster than others do), the main problem is the aspect ratio. If this can be resolved then I would have a number of other requests regarding mpg playback.
thanks for yhe attention

Ok, thanks. The playback seems to be good, i have a 768x576 video size... like media player

Old Versions of Windows Media Player did not playback using the derrived resolution either. Could you be using an old version of WMP?
I have uploaded two new files.

mpc.gif show how Media Player Classic (Not Windows Media Player) renders the aspect ratio. xnview.gif shows how xnview renders the aspect ratio.
I think it is clear in these pictures that xnview is rendering the aspect ratio different to media player classic (16x9).
