It only changes the numbers a bit, but still a lot of errors.

Without harddup:

It should only lead to missing frames, not crashing the player? Also,
using rawvideo output and doing pulldown with another program produces
a good stream, even without harddup.

I guess there's no point including audio with all those errors?

Yes, it's 0.6.11.
