If the content has to be decrypted in order to be used, then the answer 
is generally yes.  But not because of the algorithm used - most attacks 
don't attack the algorithm anymore, they attack the decryption mechanism.

For someone with the skills, extracting the necessary keys has become 
fairly trivial.  How long did it take for HD-DVD and Blu-Ray DVD 
encryption to be "broken"?
