Hmm it looks like your pointers to the perfmon Counters are corrupted, you have to rebuild these with LODCTR from a elevated command prompt:

Close resource monitor

Click Start, and Click Run and type cmd
At the prompt, type lodctr /r and press ENTER. This will repair the pointers with the system backup store.

This will definitely solve your problem.

Strangely enough, I opened resource monitor again to do this, and now it's working! (I just fixed some broken shortcuts in the Public folder where the videos were - I don't know whether that had anything to do with it.)

The question now becomes, why is media player thrashing the hard drive? I've got 16Gb of RAM, but looping a 45MB video causes WMP to constantly read the file from disk (that's the 4Mb/s shown earlier).
