I discovered that my recent Kodak DX 4530 Easyshare camera only takes movies in Quicktime, when I was at the Bargoed Festival over the weekend. The supplied software only plays them, it does not convert them in any way. Silly really if you want to share it with people or put it on the web.
I have found an older program called Quicktime Pro 61, this will export Mov files to AVI or MPEG.
