I have been building a flash video player based on a combo of go to and learn's flash video tuturial and adobe's http://www.adobe.com/devnet/flash/articles/prog_download.html tuturial for a dynamic progressive playlist. Everything is working except the thumbs are not appearing. Instead it says "type function" in the list. The list is still selectable and corresponds to each progresive video. Has anyone worked with that tuturial?
