Software suggestion for for burning video/audio at slower speed?

I am looking for software to utilize video that I have taken, and burn a disc at slower speed, keeping the pitch of the audio the same. Is there software out there that will do this (easily and possibly for free)? Thanks

If you have you vids on your pc in a normal format then this should work for the creating and burning http://www.afterdawn.com/software/audio_video/video_editing/dvd_flick.cfm
