You should also pay attention to the size of the files. i.e. for a full length film, you should be expecting something around 700 MB (500-1,000+ depending on length and quality of encoding). Sort your files by size after you do a search. This will help you pick out some of the fakes, also. If you see several or many differently named files all with the same file size, and you can't download one of them, you won't be able to download any of them.

Hope this helps
