Jerky FPS videos that MPC reports as 30FPS and VLC 60FPS. madVR reports repeated frms

I find a few 1080p videos on the web that for some weird reason they are reported 30FPS on MPC and 60FPS on VLC. Now the thing is in BOTH players they seem jerky in playback, like they are both like 15 or 20 FPS. madVR also seems to report around 15 frames a second being repeated.

What's going on? Is the source bad? Do I have to handle it in a special way? I currently suspect that the source is only 15FPS and it pretends it's 60, but I'm not sure. It's weird because they are 5GB for 50 minutes so they should be good quality.

They are mpeg2/ac3.

CPU or GPU do not seem saturated when that happens.

I've tried LAV latest, LAV a couple of months ago, whatever VLC does,

dayme... even windows media player does the same "15-20 FPS" thing.

It does not fix on GPU decoding on LAV while the GPU usage is not saturated.

lal, now even mplayer.exe doing it? Now I definitely suspect the source being bad. I heard several 1080 TV sources are bad compared to 720 due to bad encoding.
