I am looking for application that will help me organize movies, clips and other videos I have.

I tell it a folder to watch, and then I can mark every video there as watched/unwatched, set rating, add description, tag it. And possibility to open with preferred video player (for me — VLC). Option to get all info from imdb or other source will be very good.

yFlicks would be a good one, but it uses quicktime, so it doesn't like any non standard codec and container (for example mkv), it doesn't work well on Snow Leopard.

Any suggestions?
