[BUG] SRMD causes crashes

[Selur]

The error, basically sais that the decoder crashed.
Looking ath the vapoursynth script used

clip.set_output()

I see no problem. And the script works fine here.
Even if it's terribly slow. (0.4 fps here)
Does the Vapoursynth Preview work fine?
My guess is this is related to the beta and the graphic drivers.
