Stay away from files with heaps of sources (up to 100 at times), these are the most likely to be fakes. The ones that sit 'connecting' forever & then go straight to 'need more sources' are usually fakes.
Try the All Types search, look for movie title - format you like (eg movie - avi). Also search for actors' names, or even the director's name. Search at different times of day, as users in other time zones log on & off, new files become available.
