It says "Microsoft PowerPoint Movie" which is exactly what it is... So I guess that's the "unsupported file type" which I can't put on the DVD now, that's really too bad...
Wouldn't that be a simple fix in the software to allow all kinds of .mov files, no?
I don't have QuickTime Pro and I hate when I have to buy extra stuff just to make something work, arrgh! But thanks for your quick reply! I appreciate it.
