Late last year, around April they decided to block ChiefDelphi, The Robonauts Website, and one of the FIRST sites (home or Q&A I don't remember), so I told one of the techies at school who helps out with robotics and he got them unblocked.
Also for those that try to get by the schools' settings, at my school at least, you can get suspended from school and lose computer/technology permissions for the rest of your high school career for using proxy servers, whether for CD or YouTube, schools have blocked stuff for a reason, and if you have a problem with it or you feel that there is something that was unnecessarily blocked, talk to your robotics teacher sponsors and maybe an administrator or something because it works, and even if it takes two to three weeks to get CD unblocked or something else, (YouTube will never be unblocked by the way...there are reasons due to some of the R rated clips on the site), it is completely worth it.
By the way here is the
Vid you requested and if you need any help or have questions give me a PM on CD or AIM.
Pavan.
