I just started using tv_imdb and its pretty awesome thank you but I hit a bug. I thought I'd try and track it down as my way of saying thank you :)
I noticed that 'Toy Story' and 'Toy Story 2' were on and it found a match for the former but not the latter. I think the problem is that there's a video game of the movie for Toy Story 2 released the same year and they happened to be in the order such that the video game overwrote the movie. It subsequently skipped the video game and found no matches.
-bash-4.2$ grep "Toy Story 2" moviedb.idx
toy%20story%202%20%281999%29 Toy Story 2 (1999) 1999 video_game 0873201
A simple fix might be to filter out video games when building the index in the first place and anything else that's going to be ignored.
