It's great, you can order the LM Series at Instanbul, Spa, Nurburgring and Donington so far, all for 1.99 each. The downside is the quality of the video. It doesn't look so good when full screen but It's damn worth your 2 dollars. They also have Fia GT if you're interested.

By the way, if anyone here knows where to get your hands on some LeMans dvds, including ALMS, LM, Fia Gt, I'd appreciate it.
