I am not in the business of making DVD's of the episodes I download and then selling them. I just download it to watch it commercial free. I already pay for my internet connection and I pay for cable TV.
The same goes for Movies. I mostly download old movies, if I really want to see a new movie I will go to the theatre and see it on a big screen. Otherwise I am downloading old movies. What is the difference of me downloading a movie from 3 years ago, or watching it on TV? Sure the cable company paid for the rights to show that movie, but I also pay the cable company for my internet connection. In the end the cable company is still getting my money. Which in turn the cable company pays for the rights of the movie.
