Semantics
I realize a lot of you are really into saying that what this person did wasn't stealing, and semantically and legally (at least in the US and apparently in the UK) that would be technically correct. However, You're just nit-picking. What illegal copying and sales/distribution of movies and music does is deprive the legitimate owner of the IP of income, and in this case, making money by selling something that doesn't belong to the seller. To me, even though the guy making and selling the copies didn't deprive the owner of the physical movie he deprived him of money that could have been made from people who wanted to see it and maybe have their own copy to watch when they wanted. That may not technically be stealing, but it's certainly a kissing cousin of stealing.
