Where Can I Find A Video Converter That Converts .wma And .ram Videos To A Mac Compatible Form?

I bought a Mac not too long ago and am finally getting around to moving files from my old PC to my Mac.
I need a video converter that can convert all my Windows Media videos and my RealPlayer videos into Mac compatible forms (.mp4 .mov etc).
Most importantly I need the most dummy proof, easy to follow converter. I know practically nothing about codecs, add ons, plugins, the “Terminal” application, and all this other crap.
I just tried FFmpegX. I downloaded it, along with all the binaries and add ons and it isn’t working.
Like I said, I’m a complete idiot when it comes to computers so I need a video converter that has NO learning curve whatsoever.
I don’t mind paying for one either, assuming it’s easy to use and actually works.
