Making copies of video from DVD and TEACH Act

[Jeffrey La Favre <jlafavre@xxxxxxx>]

I am in the process of trying to understand the TEACH Act.  
In particular, I am trying to decipher the meaning of 
section 110(2)(D) of copyright law: "[The institution]does 
not engage in conduct that could reasonably be expected to 
interfere with technological measures used by copyright 
owners to prevent such retention or unauthorized further 
dissemination;"

It would be of great advantage to copy video from DVD in 
order to make clips for streaming from a media server.  
However, my understanding is that nearly all video on DVD 
has some type of digital rights management (DRM). For 
example, 
Content-Scrambling System (CSS)is used to prevent the making 
of a digital copy. It is not difficult to get around CSS 
when importing the video into a computer for the purpose of 
making a video clip.  But when this is done, the clip no 
longer contains CSS. If I make a video clip in this manner, 
am I engaging in conduct that  interferes with a 
technological measure used by the copyright owner?  If so, 
then it seems to me that very little copyrighted video (or 
audio) can be provided to students according to the TEACH 
Act.  Why? Because nearly all video and music on CD has some 
form of DRM. And in order to make copies for streaming, one 
will invariably remove DRM from the medium. So then the 
TEACH Act is essentially worthless in its provisions to 
allow 
the streaming of video and audio?  What am I missing?
