If it's a legit copy then I don't think it will be a problem. For example, sa Blu-ray, I can grab the media from the disc to my laptop and to my mobile devices which as an owner is part of the features that comes with the goods I bought. As long as I can show the original source, there is nothing to worry.
What I'm concerned with this law is the timing. Its a little bit late now to implement this. With the emerging cloud computing, goggle drives, sky drive to name a few, and the emergence of free and subscription-based online streaming, why bother carrying hardware around.
