I hate the search for converters. It could be video, audio, images or whatever. There are many formats, and sometimes, it's hard to get the right one. I have found some converters that I usually, use (I might give you a show around of my mac and PC some time), but what if I don't have them avalible?

I found an online converter for you lazy bastards.
I haven't tried it yet tho, so if your computer dies of virus, I WILL NOT BE RESPONSIBLE.
But yeah, it's a pretty good idea at least.

I got like 1000 words to write before I go to bed, so you'll be happy with the link. I'm not in the mood to be arguing with <iframe> right now.

Hope it's of help!
