Dreamscene stops when using AVI files...

I just recently decided to try Dreamscene. When I select one of the scenes
that uses an AVI file it plays one time and then instead of looping it stops
and I get the following error: "Dreamscene has encountered an unrecoverable
error while decoding the video."

I have googled it but only cam up with some year-old web pages relating to a
Roxio problem. I'm not aware that I have any Roxio products. Also, I went
to the Roxio site and searched for anything related to Dreamscene and didn't
get any hits.

I also looked for a Dreamscene site but didn't find anything.

It's no big deal if it doesn't work since I don't see why I would spend the
CPU cycles on it but I am curious about why it doesn't work.

Has anyone heard of, or experienced, this error and do you know how to
resolve it?

Thanks in advance,
