Is YouTube Blocked at your school, use www.zamzar.com to convert videos to mp4 files!
Here's how: http://tonyvincent.net/?q=node/33
You can also use idesktop.tv to search the You Tube database, find a video you want to use, download it to your account (you will need to open a free account first) and then download it in the format you want (.wmv, .avi, .mov. mp4 etc) to your hard drive. It's faster than Zamzar and you wont' get caught up in the queue, which can take hours.
