Diver,
I was informed that the DVD you bought from Megamixx was consigned to them and they had no idea that there was no official release of that DVD. It was a mistake on their part but they have no intention to fool the buyers, that I do know. Had they known it was not an official release, I'm very sure you won't find it in their inventory. The store do not sell any pirated DVDs.
You could probably go back to the store, like some members suggested. I'm sure they will not turn you down. If you're uneasy with going back and asking for your money back, let me know. I might be able to help you out.
Just want to clear this out since people might get the idea that pirated DVDs are already available at Megamixx.
Thanks!
PARC
PS. Sending you a PM Diver.
