"In-Car Active: Silverstone" DVD - where can I get it?

[JonRB]

I'm doing a track day on the GP circuit at Silverstone at the end of the month and have been recommended this DVD to help learn the circuit.

Trouble is I can't find it anywhere to buy. It's produced by circuitdriver.com but their shopping cart system is up the spout and won't let you order, their "contact us" page just gives you an email address which isn't answered, and their list of stockists (which include PistonHeads) yields no results in each case.

In short I'm stumped on where to buy it.

Does anyone know who stocks it or has a copy that they no longer want and might sell me?

Thanks in advance
Jon
