Will KeepVid.com work on your hosting site?
No. I tried. Good thought though.
I have a new copy of Shockwave Flash Studio at home I haven't loaded yet. When I get home after work I'll load my .swf file and see how I might be able to manipulate it with that software.
So far, all converters I have tried have puked when trying to convert the .swf to any other format.
