Be more specific, for example genre or whatever makes the episode you want different from episode five of season 1. Being as specific as you can will make it more likely to get the episode you want. Doing a general search for the series you want can be useful too.

It seems to happen most often when I do searches for H e r o e s, and D e s p e r a t e H o u s e w i v e s. It doesn't matter if I type in a general search or if I go specific. For Example, if I type in a search for Heroes season 1 episode 8...I still only get a hundred results for heroes season 1 episode 5, 3 and sometimes 21. The same thing with D H. I get hundreds of results but for the same one or two files. Ive tried typing in the season first and then the name of the show but as soon as I hit search I get the same nonsense. Ive even sat for hours hitting the get more results option from the drop down menu, hoping that it would eventually hit on the real files, but no suck luck.
