Interesting Dilemma – Can you Download YouTube Videos and show them in the classroom?

I would LOVE comments on this.

Our district blocks YouTube at the current time.  Of course, students, especially but even teacher have found ways to circumvent the block.  However, circumventing the block violates District Acceptable Usage Policy.

So does going home, using your home internet and downloading a video, mean that you have circumvented the block.  Technically yes, but it is not against district policy to do so, I asked. 

Here is the caveat:  I do have to be careful that everything I show is classroom appropriate and fits within my curriculum. 

I believe I should also make it clear to my audience that I am using my own internet, and not the district internet and why.

HOWEVER, downloading the video and not using the YouTube service DOES violate their Terms of Service, so I should not just download the video.  I do need to use my own internet. 

I think.

Am I right?
