I wonder if you copy the movie to /dev/shm first (so disk I/O is not an issue) does it still have problems? At least this can potentially eliminate disk I/O as the cause if something else weird is going on. :) For the problem of massive amounts of RAM consumed, that's strange. Are you compiling debug symbols? That can make the RAM usage (in linking especially) explode...
