I must have "watched" 9-12 dvd a day. 8)
Hehe, good one.
Those DVD's are copy protected, and it's not just blockbuster that does this. Most DVD's on the market are copy protected. Yes it is illegal to make copies of those DVD's, but there is supposed to be third party software to do it.
I advise against it though. Save yourself some hefty fines and possible jail time and just buy the damn DVD's. 8)
