4# This perl script is intended to perform movie data lookups based on
5# the popular www.imdb.com website
6#
7# For more information on MythVideo's external movie lookup mechanism, see
8# the README file in this directory.
9#
10# Author: Tim Harvey (tharvey AT alumni.calpoly DOT edu)
11# Modified: Andrei Rjeousski
12# v1.1
13# - Added amazon.com covers and improved handling for imdb posters
14# v1.2
15#     - when searching amazon, try searching for main movie name and if nothing
16#       is found, search for informal name
17#     - better handling for amazon posters, see if movie title is a substring
18#       in the search results returned by amazon
19#     - fixed redirects for some movies on impawards
20# v1.3
21#     - fixed search for low res images (imdb changed the page layout)
22#     - added cinemablend poster search
23#     - added nexbase poster search
24#     - removed amazon.com searching for now
25
26# changes:
27# 9-10-2006: Anduin Withers
28#   Changed output to utf8
29# 30-6-2007 fix for new imdb.com design
