Judging by all the fan videos made. There must be a good and reliable video converter out there. I was given a couple suggestions and googled a few to only find trojans or other malicious files within them.
Thanks ahead. 
SUPER
No malware in there.
Media coder converts everything! and it’s free and very powerful. It even uses cuda.
Dammit, Dillxn ninja’d me. ^That, 2nded.
Any video converter is what I use too
Prism is nice.
I’ve always kind of fancied Format Factory.
Use to use SUPER, but that stopped working when i made the switch to windows 7.
Really like Format Factory though, use it for those high quality mkv files.
I use any video converter here too. oh and RAD video tools, with RAD you can change anything to AVI to be able to play any video file on your divx dvd player.
That may be good for your dvd player…
but for the computer it’s best to use the Xvid codec when doing avi files.
It’s free open source, and it’s not owned by the evil divx cooperation.
With RAD you can change it to Xvid or any mpeg4 codec you have on your computer.
I use SUPER and handbrake!
Youtube downloader lets you download videos from youtube AND can convert video files into many formats.
If you don’t have it, you may want it. Can be handy.
Avast and spybot search and destroy found malware associated with the program youtube downloader so… avoid that one.
Really?
Glad I only installed it on the school computers then. 
Okay, I got nothing.
SC Video Converter
However it appears all downloads point to a single download page that is currently down. hrm.
