I'm using Grand Perspective to see where all my space is going, and I have a folder (or file) taking up a gig. It's called "private/var/vm/sleepimage. Anyone have any idea what it does? Also, one more quick question, if I get a hardware error when burning a VIDEO_TS folder, does it mean there's a problem with the file? It works fine to watch it from the harddrive. Thanks.
