Revolution does not give you access to the matrix property of a movie 
or track.  If you don't have too many movies to deal with you could 
mirror them using QuickTime Player Pro.

In case you haven't done this before here is how you would go about it.

1) Open the movie properties window
2) Select your video track from the menu on the left
3) Select "Size" from the menu on the right
4) Use the buttons along the bottom of the panel to mirror or rotate.

If you have to show the movie both normally and mirrored then just save 
the mirrored version while allowing dependencies.  This will save a 
small reference movie which points to your original movie but plays it 
back using mirroring.

If this isn't a practical solution then an addition could be made to 
the Enhanced QuickTime external available at my website -

There seems to be quite a bit of matrix manipulation calls in the QT 
API.
