"Single or Dual Layer mebejedi?"
Single. I don't have the funds to get a dual-layer burner yet. I still have the master files, though, so a future DL version is possible.
In fact, if I can get my MPEG to be 100 megs smaller, I can add my 5.1 soundtrack as well (not a big deal, really, but I am re-encoding from an average of 3,000,000 to 2,995,000 bits, just to see if it's enough.
) PCM, 5.1 (at 480 kbps), and the commentary track. Not too shabby, eh? 
"I posted your other stuff off today too"
Cool! After this little experiment is done (it takes 18-20 hours), I'll send my current version to you and Rik.
