What Benni-chan said. Couch Potato will sort and rename the movies into folders to a specified location. I actually used it to do a complete initial sort and rename on all of my ripped collection too. Just rip your DVD / Bluray / HD-DVD and drop it into the watched folder (the movie itself needs to be in a folder of its own). It doesn't have any "Library" similar to SickBeard, but it certainly does more than just look for and download movies.
Not quite sure I follow on watching for a new series. Are you referring to watching for sequels for movies (Harry Potter series, or any new Ghost in the Shell movie, etc)? Never seen anything that could do that, and honestly not quite sure how it could be accomplished. Since TV Series tend to have expected seasons with specified air dates, being able to watch for these is easy. Movies tend to just be one offs, with the possibility of sequels being up in the air. Maybe I'm not understanding what you're asking???
Sickbeard for TV + Couch Potato for Movies + Usenet is the perfect combination for me.
