Technical Difficulties

So, I've been trying to upload my skydiving video to YouTube all day long, but to no avail. So, the question is, does anyone have the know how and time to explain it to me? I haven't been able to figure out all that I need to figure out on my brother's mac computer. So, while Macs are great, they are foreign to me. If all else fails, once I return to the Mothership, I'll at least post pics. Sorry for the delay. I WISH I COULD SHARE THIS STUFF, ALREADY!
