Hi,
The ">" character you have in your example below shouldn't be there,
that would cause some trouble for sure.
Here's a proper example command sequence to make a movie from text mode:
package require vmdmovie
mkdir /tmp/mytmpdir
::MovieMaker::makemovie /tmp/mytmpdir example ppmtompeg snapshot 10
This worked fine for me.
Try that and let me know how it goes.
Cheers,
John Stone
