Converting DVD to innotab 3s

[geordiemoo]

Hi, I'm desperate for some help. I had been doing this very successfully using dvd catalyst however the software got corrupted somehow and now cant be downloaded. I've downloaded the spiffy converter and ffmpeg but can't work out how to use it. I've been trying using various software for 3 days and I'm slowly going mad

What format is the dvd. Is it on your PC or still just the disc? Can you give me a link to the spiffy converter software you got?
