Quick update before I really've got to leave:

Got a working phone number from pg (thanks Jareth@pg).

Now take a breath: At the phone I was told that they have got no information of a 99$ DVD-Upgrade, the only thing they have got on offer is the 139$ USB-HD. So it is impossible to order via phone, there is no download option and no online store for it.

What is that supposed to be? Common PG, don't mess around with us!
