I'd deffo bring all DVDs and CDs, especially if you watch your DVDs on your laptop. They're great for the plane if you get stuck sitting next to someone annoying and you don't like the in-flight films. Also they're good to have around as a pick-me-up if you feel lonely or homesick and/or you have no TV.
I also brought some stuff to make any place feel like home - some small Aveda travel candles, a small photo album, a necklace my father had given me, some shells my mom found for me, some drawings by my nieces, a book of photos from my fav national park, etc.
