If you plan on going to Blu-ray you should just use the THX patterns on a THX mastered DVD until you get a Blu-ray and then get the HD DVE (Blu) or the Spears & Munsil disc. If you're sticking with DVD then use the SD DVE. Do not try to use GetGray unless you have no trouble reading and understanding the manual.
What you've heard about DVE is (or should be) with regard to navigation when doing pro calibration. It's not relevant when you're making adjustents by eye.
