I received PowerDVD free on the installation CD for a TV tuner card. You could safely assume that I have legally obtained the software and have registered online. The CD key listed on the website for my product does not fit into the CD key pop up whenever I try to use the software.
This seems to happen to others and there doesn't appear to be an answer to this mystery on the forum - German or English.
I wouldn't recommend this software considering the difficulty that I, and other users, have experienced.
