My copy arrived this morning and I had to watch it right away:-) Thanks to this forum for drawing my attention to it.
It has been the first 24 hours race I visited back in June and besides the freaking cold and wet wheather from Thursday to Saturday (what did I expect:-) ) it was an awesome experience. I started to visit VLN races afterwards and will for sure go on watching those races at the ring.
The movie itself is pretty good in my opinion. Maybe the part about the race could have been a little longer but this is probably just me loving to see as much race action as possible

Otherwise I really liked all the background information and filming from drivers getting ready, testing on different tracks and the work of the mechanics. The atmosphere especially on the race weekend is really good and you feel like standing in the pits next to the cars and drivers getting all the emotions.
I ordered the Blu-ray and the quality is worth it. This might be as well just me cause I do not have too many Blu-rays but it is such a difference to non-HD programs.
There is some additional material on the disc. For me the most important part was for sure the onboard lap around the whole track.
I hope my little review is providing some impressions to maybe make the decision easier whether to buy it or not.
