Hmm couldnt find an "About" box last time I checked. I have no idea where do I look for ffmpeg and what these switches are
The exact packages can be found here:

Tversity's ffmpeg is v0.6
The codec pack is also listed in the above link.
I just realize they have a free version and a Pro ($$$) version. That kinda makes me a little suspicious. You can try their 30 day money back guarantee to see if the paid version solve your problems.
