My flying buddy also has a BEVRC DVR. His seems to crash more often than mine. I'll ask him what card he uses (although I'm pretty sure his is a class 10 as well).
They only seem to freeze when the video signal becomes noisy followed by a total loss of signal. We fly quads on 5.8Ghz so flying behind a row of trees at long range is enough to make it freeze. (Crashing your quad most certainly causes it!) Apart from that it records for long periods without fault. I think it has more to do with loosing sync (to many interrupts?) than writing to the SD card.
