FREE Audio and Video Format Converter - WinFF

Looking for a Media Converter
I had some unprotected ipod style m4b audio book files that I wanted to convert to MP3 format for playing on the Blackberry and other sources. In my search for free software to do this with, I found WinFF. WinFF does considerably more than I originally needed but as yet, I haven't tried it with anything other than m4b to mp3 conversions.

Availability
At the time of writing the latest stable version was 0.43 (and this worked well for my conversion). I tried version 1.0 for Windows but either I didn't allow it enough conversion time or there was a problem.

You can get the software here; http://winff.org/html/downloads.html

The software is Open Source and is available for Windows and Linux (Ubuntu, Debian and Redhat).

Usage
There's a manual available on the site but it's not terribly detailed. Using the program is pretty simple though, you simply "ADD" your file to the list and then pick a conversion type (Audio or Video). Then you choose the output types (eg: MP3) and an output folder. When you click Convert, a DOS/Command Prompt window opens and conversion starts.

Summary
It took a long while (about an hour) on a 3GHz P4 to process a 283 Mb m4b file into an equivalent 666 mb mp3 file (obviously MP3 is a format with lower compression) but unlike all of the other (apparently free) programs I tried, WinFF made it all the way to the end.

I'm not sure if it will handle "protected m4b" files or how it handles all the other formats but this program is a keeper, so I'm sure I'll find out sooner or later.
