Hopefully this link will help. Bitzi allows you to check files before you download them. It works very well for movie files. Any movies that have close to 100 hosts are most likely fake. Go for files with 10-20 hosts or less. If Bitzi doesn't have any information on the file and it has lots of hosts, it's probably fake. If Bitzi doesn't have any information on the file and there are very few hosts, perhaps the movie hasn't been rated yet.
