Can't seem to convert a rm file

[arcureo]

Hi... I have to convert a real media video file (not streaming, it's a 22 Mb file located on my desktop) into whatever it fits... say a mov file...
I followed every step on the ffmpeg site to get all the libraries (for real media, too) but when I try to convert it I get a zero byte file that won't (obvously) open...
And it takes just a few seconds to convert it!
Way too little time for al eighteen minutes video clip, right?
The strange thing is that when I load the rm file into ffmpeg and I press the preview... it actually plays! On the web page it says that if you can play it on ffmpeg it means that you are gonna get it converted... but all I'm getting are those "fake" files...
What gives?

Here's the message I get if I get the in fo about the conversion...
