Bug: The search engine no longer finds any movies when searching for a new movie to add.
Cause: IMDB.com updated their search algorithm which in turn broke Izzy's "IMDBPHP" code. (This is used in PHP4DVD when searching movies)
Fix #1: http://projects.izzysoft.de/trac/imdbphp/ticket/306 (Read this ticket and apply updates manually to the code within PHP4DVD)
Fix #2: Download the attached file and replace php4dvd->lib->imdbphp->imdbsearch.class.php with this attachment.
