It was most noticeable in [Ayako]_Seitokai_Yakuindomo_-_08_[720p][H264][43B95F18].mkv, though all of them exhibit the same problem to some degree.

Time is, well, it's a every time the little title card comes in and does the red-stamp effect, there's softsubs translating the stamps. That's when it drops frames.

I am using ffdshow-mt to decode (so it's multithreaded), and my CPU isn't scaling up the multiplier much, so I don't know exactly how much power it's taking to decode. Task Manager shows 20-30% CPU utilization for most 720p H264 encodes, but CPU-Z tells me the CPU isn't even ramping up that much--multiplier stays at either x11 or x13, clockspeed stays at or below 1.7GHz. Spikes a bit here and there, but generally stays around that.

Edit: Worst bit is 16:55-17:00. Really obvious there. Multiplier hit x20 at that point, but utilization stayed below 35%. Must be borked subs.
