In addition to what has already been said, I would like to add that it is very dangerous to use P2P for movie downloading in the US. The MPAA has a zero tolerance policy. It has been noticed that even the downloading of a single film is enough to draw the wrath of Hollywood and a resulting lawsuit or nastygram from your ISP.
Unlike the RIAA which is bad enough, the MPAA does not just go after up loaders with thousands of files in the share folder, they will go after any IP address they happen to snag that is merely making a download.
If you live in the United States and want cheap movies, I highly recommend, Blockbuster Online. You can get a ton of movies delivered to your door for a small price. But the kicker is they will send you up to 4 in-store coupons per month. (one a week) that you can use for games or movies. If you think about it, this is about the price of the monthly service which is 18 dollars total for the most expensive plan. As movies are 4 dollars a pop. Add this with unlimited rentals, 3 at a time delivered to the house and you start to get the idea this is a good value.
In addition, if you couple this with the 10 dollar a year in store "Rewards Program" you can kick some more ass. Here's what you get- Remember a rental is 4 dollars regardless at Blockbuster. Since I have the online program, I never pay for a rental when I visit the store I use just the coupons. But it still enhances your online program as they work together.
Your first movie or game rental free.
One free non-new movie or game rental every month.
One free non-new movie or game rental for every rental made Monday through Wednesday.
One free (new or non-new) movie or game rental when you rent five movies or games in the same month, up to two free rentals.
When I go to the brick and mortar store with my online coupon on Monday through Wednesday, I rent a new release. About half the time, they screw up and give me another coupon for a free non new release for each free movie I get that day, due to the rewards program- LOL. You always get one free one a month no matter what. At any rate, the 10 dollar program is a sweet addition to the online program, as you are down there picking up free movies anyway, so what the heck! It sure beats freaking out if you are being watched on the Internet. For 18 dollars a month, the peace of mind for me is worth it!
Yet another side benefit, is their previously viewed DVDs that you can scope out while you are there for as little as five dollars. They are guaranteed to work flawlessly and so far I have yet to have a problem with even one.
