Changing path/type of a video file?

[denx]

Hi,

is there any possibility to change the path to a video file in an
existing presentation?

For example:

There is a slide with a video path (.../video1.mpg). Now I'd like to
change the path to another file (.../video1.wmv.), so that all other
animations remain the same. For pictures I can use the option "Replace
Picture" (respectively "Bild ändern" in German).

In this special case the existing video file is to big, so I converted
it with another codec. Now I do not want to delete the old video file
and insert the new one, but simply replace it.

Greets,

Dennis
