The file seems to have exactly four UCS16 strings in it, at decimal offsets
Code:
16398: http://api.themoviedb.org/2.1/Movie.search/en/xml/{1}/{0}
16514: http://api.themoviedb.org/2.1/Movie.getInfo/en/xml/{1}/{0}
16783: http://mobile.filmaffinity.com/es/search.php?stext={0}&stype=title
16917: http://mobile.filmaffinity.com/es/moviesynop.php?id={0}
You could do a simple binary replacement using strings of the exact same length, i.e.
Code:
16783: http://m.filmaffinity.com/es/search.php?stext={0}&stype=title&&&&&
16917: http://m.filmaffinity.com/es/moviesynop.php?id={0}&&&&&
but while the former seems to work (e.g. http://m.filmaffinity.com/es/movie.php?id=988464&&&&&), the latter does not (e.g. http://m.filmaffinity.com/es/moviesy...id=988464&&&&&).
In other words, the FilmAffinity site has been modified in a way that almost certainly breaks your library in other ways, too.
