Hah, I'm in the same position my friend. I'm 14 as well and I'm almost scared to jump my MT2 off a curb. It is still new, after a month or so I'll finally just say something like, "Ah, who cares anymore?" and do something insanely stupid with it like jump it off my friends roof (it can be done, you can access the VERY top of his roof and it is flat). I have a whole bunch of hard drive space, so I could store the stuff. Hah, I could dedicate an entire hard drive for it, and it's 60 gigabytes.
It wouldn't be that hard compiling a bunch of clips into one DVD, you'd just have to have a bunch of footage. Editing isn't hard, I could do that with Windows Movie Maker.
Oh well, let me know if I can help with anything. Shoot me a PM if need be; I'll get it since I leave this minimized on my desktop practically the whole day.
