So I've decided to rerip my movies for the iPod at the 640x(n) resolution and I noticed some giving me problems. Normally it takes ~45min for a 2hr movie to encode, but these are taking 13hrs and I don't see why. So far the only movies I've encountered are "The Thing" and "Fear & Loathing in Las Vegas". Right now Cowboy Bebop is going at the normal 45min speed. The settings are nothing unusual from the last time I ripped movies.
