Hmm... I guess the correct thing for me to say would be make sure the EXTENSION is flv. Judging by you saying that it opens in IE, my guess is that the extension is .htm or .html. Try this: Open the folder the file is in and go to Tools > Folder Options. Click the "view" tab, and uncheck "Hide Extensions for known file types". Then click OK, and you should see that your file is named (...).flv.htm or (...).flv.html.

[edit]Just so everyone knows, I will be gone today and tomorrow and will not be able to work on the GUI at all. I'll try to get bugs that are reported over the weekend fixed on Monday.
