I bought and downloaded a program called Wondershare Pro that lets me rip the video from the dvd and convert it to whatever file format I want. Then I open it in iMove HD, which is bundled software on my Mac. That's where I add the transition effect at the beginning and end of the video and do more editing to the frames.

Then, I open the file in Adobe ImageReady. There, I can adjust the timing of each individual frame, so I put a few seconds of delay on the first and last frame.
