A couple things to note:

1) There is a tooltip for "File Type" which I am applying a combination of the copy in the specs requirement and my own description. I think it's as technically clear as I can make it. Let me know if you're good with it.

2) I've reviewed the previous Flash Gadget code and I think I might see a way to eliminate the need for this File Type selection choice. It could be simplified to just have a disclaimer about the type of SWF a user will be using to remind them about how it applies to the Player. The disclaimer could actually be similar to what I am using for the tooltip. 

Let me know what your preference is - keep the File Type selection or remove it. I wanted to give a heads up now so that there are no surprises if you see the File Type selection dropdown is removed in the next pull request.
