Erm, they didn't put it there in DVD format, they just had the files.
Are English magazines as crappy as American? I've seen some PC Gamer issues and subscribe to CGW, but they suck greatly compared to what GameStar or the other German mags put on their DVDs. Usually they separate DVD content (playable in any DVD player) from files. They have game reviews done by the mag's editors, game trailers, movie trailers,
fun videos by the staff using blue screen, specials... A GameStar DVD is good for several hours of entertainment, the CGW DVD usually lasts minutes (Pure Pwnage flicks being the exception).
