No, he's apparently already unrared the files, as he's got the ISO file. I don't know what the problem could be. It is possible, however unlikely, that your laptop indeed can't burn DL-DVDs. You may want to try and burn on someone else's computer.

Here's a guide anyway:

Well, I downloaded both the HD version of ANH and the SD version of ESB; after burning both to DVD, the former won't play in my BD player and the latter jumps around like Yoda in a fight. A rip of ESB off Handbrake plays perfectly, though, so the problem is clearly with my DVD-RW drive.

With that said, what I've seen of ESB is beautiful. You're a generous man, Harmy...thanks so much! Now I'm anxiously waiting for ANH SD to download and RotJ SD to get posted.
