3gp encoder for mac?

[ImNoSuperMan]

Is there any good free software which can convert wmv,mpeg movies to 3gp? Right now I am using ffmpeg. Even though it has the option for 3gp but whenever i try to convert any file it just creates a 0kb file with nothing in it.
I m using an iBook G4 with Tiger.

i use toast 7 to convert video and dvds to psp and 3gp format.
it's not free... but it works.

Sorry for the bump, couldn't find any other threads regarding this topic.

Anyone know of any Software besides Toast?

I don't know of anything free, but QuickTime Pro will cost you less than Toast.
