What are some good books that I could read about light weight backpacking? So far I have read Lighten Up and Ultralight Backpacking Tips. Both had great info. Are there any DVD's out there on the same subject?

There's the classic by Ray Jardine. Latest version is called "Trail Life".
Some of the stuff comes off fairly opinionated, but still well worth reading.

There is enough information here on BPL. Just pack your gear and start hiking. Experience is the best teacher.
