Need to find a disc or download of Presto! Mr. Photo AND Presto! VideoWorks for my DXG-572V camcorder. Needs to work on Windows 7, or I might be able to try it on an old Windows 2000 PC that I still have access to. Can you please email me asap to tell me if this $49.95 download will work, or if I can get a full refund if it does not work with my camcorder?
