Gosh, I didn't know the DMCA went that far. I had assumed it was in line with Canada's TPM related laws which do disallow direct circumvention of DRM but do specifically except format shifting if the copy will be used for a legal purpose. I guess be careful and check your local jurisdiction.

The US Library of Congress is given a Special Exemption in the DMCA [1] and so far the Library has been using it to grant a Backup Exemption that format shifting is legal for backups. Due to the nature of this exemption it has to be debated and reviewed every 3 years, so it's in a weird legal status if it "will always" be around.
