How can I convert a flv video file into a screensaver (scr file)?

I used many online converters but I always loose quality. Does anybody know of a software I could download that I could adjust the size and change audio and edit the file before I make it a screen saver. I have a software called instant storm that can turn the file into a screen saver but the file has to be a SWF file. Any help would be greatly appreciated.



P.S.

I also tired to use windows video screensaver but had problems installing it.How can I convert a flv video file into a screensaver (scr file)?
