Latest MPC-HC, some 720p videos stutter despite good GPU and CPU

Sorry if this isn't the right place to ask. I've been googling for a while and just can't find a solution that works for me.

MPC-HC is playing my 1080p videos flawlessly, yet I have a handful of 720p MKVs that are very choppy. They appear to be H.264 video, AAC audio. Actually just the video is choppy, audio is fine.

These same MKV's play back fine in VLC, so I'm sure this is just a setting thing. The hardware is a Core i5-4460 and an R9 300 video card. Running win7 pro 64.

I'm wondering if it has something to do with the program failing to take advantage of my GPU?
Here are the fixes I've tried so far.

Uninstalled all codec packs, ffdshow, etc. I actually just reformatted so I've only installed MPC-HC, VLC, and the latest video card driver.

Options -> playback -> output -> tried Enhanced Video Renderer (custom presenter) and also System Default.

Options -> internal filters -> video decoder -> hardware decoder -> tried DXVA2 (native), NVIDIA CUVID, and none.

No custom shaders have been added or enabled.

Any ideas? Again VLC plays these files fine, but I would like to just use mpc-hc for everything.

Here's the codec info if it helps:
