If you look at the bottom of the Downloaded images, you can test the the movie maker. Movie maker fires up but no movie is made.
And you can not play your last movie.
If it’s something like the animated satellite image that you’re trying to create then you don’t need anything ticked or added to the area below the “Upload the selected animated gif…” tick box.
I’ve not used the videodownload.wmv settings which the “Test Now” button is for.
Are the images being downloaded OK into the download file in WD?
They should be named something like sat.jpg, sat1.jpg, sat2.jpg…
It may also be helpful if you could post a screen shot of your setup page.
