Use Burn (freeware) or Toast (problems, though, compressing long movies in 'movie only' mode) — although you can use DL discs if you don't mind the expense.
I'm also thinking of trying DVD2oneX2 — any recommendations on this one? The price ($55) seems a bit high for burn software, but if it will compress longer movies onto standard DVDs, it may be worth it.
Also, I've been running my rips through HandBrake to get them down to a more manageable size for burning. It works wonders — The Box went from 6.4GB to 1.9GB after HandBraking it, and 2012 went from 7.8GB down to 2.9GB.
Don't let reality interfere with your life.
