@SuperFrank IPtorrents, FileList and HD-Torrents are good sources, you normally can find all region based raw BD releases for new movies there, maybe not all movies but the chances are very good with these 3 trackers, then there are good Chinese HD trackers, like M-Team, HDChina, CHDBits - but its not easy to join those (Chinese) trackers, i would just try to get the other 3 i have mentioned
