Which SE DVDs do you have? The ones from 2004 (with a single bonus DVD for the trilogy) or 2006 (with a bonus DVD for each movie)?
I understand what it is that you feel towards giving money to Lucas. Personally, I couldn't process how the hell is Hayden Christensen appearing in a 20+ years old movie the first time I watched Jedi. But it's a fan edit/preservation rule to own the sources used for making them, even if it doesn't make it 100% legal. And for v2.0 onwards, you'll even need to get the Blu-rays or whatever format it will be made from.
