[Solved] Video will not fill TV screen in both directions

[une]

When playing video on a tv screen all still pics will show as expected.
But if I have a video it will only show about 60% of the screen size in both horisontal
and vertikal.

Someone have any idea

My memory is that, when one inserts a movie to a slide, one can pull the edges/corners of the black area to fill the slide. That is my memory and it may be faulty; I usually use the system media layer to show movies, and when I invoke that I pass command line parameters to it which cause full screen usage. These commands vary according to which media player is used.

Where can I found how to do the command line parameters?

For a media player its command line parameters may be given in its Help file; sometimes these can be found by typing "<name of media player> ?" in a terminal window (no quotes, replace <name...> with name of media player)..
