Tried everything so far:
Reclock on = stuttering
Reclock off = stuttering
Aero and Vsync off = stuttering on the same places, but different then before (it stutters quicker)
Aero off vsync on = stuttering
Aero on vsync off = stuttering
again, whatever settings I choose, this doesn't happen in MPC-HC.
Which codec do you use? I have problems both with mpc-hc and cyberlink but as I said I think my problem is different.
