That's a reasonable solution because it doesn't create a liability on the provider to refund your purchase in whole. I wonder how it works on the backend. When you "buy" a digital movie, does the publisher get a royalty? Then for the credit the provider could just eat that extra cost since it likely to be very rare. It still kind of sucks that the publisher can reap the royalty payments for all the "sales" and then turn around and pull the license.
