Minecraft crash on start recording

[macoplays8]

Hi,
when I start recording and I have Minecraft on fullscreen, MC just crash without crashlog or any message. Minecraft just shut down.

My settings in Dxtory:
Codec - Microsoft Video 1
Key Frame Rate - 0
Quality - 100
Frame Rate - 60
File Format - AVI

I tried also other codecs, but nothing works.
Please, help me.
Thanks for quick response.
