It is a lot of work to create a highlight video especially when it seems like you may be looking for something in particular.
If you want to give it a try download firefox if you don't already have it. Then you can use download helper
and their converter helper(you will get a prompt when you go to download something) to grab the videos. Just go to the video page and you will see a little atom looking thing click that and it will let you download.
The converter takes a little while to work but does a good job. It runs in the background so don't freak out if you try to open the video and it doesn't work, just not finished converting yet.
Then import your clips into windows movie maker(should be on your computer if you use xp).
Then you can move the clips around, cut out parts, add transitions, music etc. Good luck.
