I do live in Denmark. The danish copyright laws are based upon the copyright rules from the european union, that all member states have to implement in their national laws. One of these rules state that it is allowed to circumvent the copy protection schemes if it is necessary to use the media. That is probably intended to make it possible for Linux users to play DVDs, but in this case it might also be used because if the user has a PC without a DVD drive, then it is necessary to rip the DVD with a different PC.
Another european rule states that temporary copies that are necessary for using the media are always allowed. Again in this case if the user has a PC without DVD-drive, then it is legal to store the DVD content on a harddrive (which is not a permanent copy).
