How to reedit a video from a dvd

[laminater]

I just went into a shark cage and wanted to post the video on facebook. They took it with one of those portable dvd making cameras. The problem is that the guy was really weird and I want to cut out all the talking parts and just insert me in the shark cage. I viewed it in Windows live photo gallery and went to "Make Movie". For some reason Windows Movie Maker shows it as an 11 second(really about 15 mins) bu t if youclick along the line to skip to parts(Im not sure what the official name is) you can reach all parts of the video. Its really weird. Anyone have any hints or advice? Thanks
