I want to know that how to download the movies in high quality? How do I know before downloading the movie that the print of the movie is of high quality?
Well usually it is written with the torrent like HD, bluray DVDscr and so on. You can also go to kickass.to where you will find torrent in multiple qualities.
Download from a trusted group and you'll be good to go (most of the time).
If bandwidth is not an issue for you then just download any valid scene bluray release (Sparks and Amiable are the best), Or any PublicHD official bluray release.
You need a fast computer to play movies at highest resolution. The HD movies with sizes around 4-5 GB may be what you are looking for.
Yes you can! If it says "DVD" or "BRIP" then it is in great quality. Otherwise "DVDRIP" is okay, "SCAM" or "CAM" are the worst ones. Never download any movie in that print.
