Always use Bitzi to check a video file before download. If other users have rated the file, you'll get some idea of it's content & quality. If a file has heaps of sources but no Bitzi rating...chances are that it's a fake. More info about fake files here.

Try varying your search terms. Use the All Types search. Search for show name - format (eg blahblah - avi). Or search for a specific episode of a series...(eg blahblah 01 x 12, when you're looking for episode 12 of series 1) or blahblah s01e12 for the same thing.
