Yeah, they're from that series. There's M-Zone Vol.9 and Vol. 11 and Mark EG Vol.10
I've heard that myself. I'm sure I can remeber Mark answering some post that asked the same thing and I'm sure (if my memory isn't too frazzled) Mark said that they were Kosher. They're alright. The M-Zone ones have some half decent tunes considering they're from 2002.
