Cannot capture time spent watching movies / listening to audio

No way to report things like watching movies, listening to audio...for instance:

Sometimes I will watch a movie on my computer. Currently it says I have spent 20 seconds in windows media player. The movie was 2 hours.

Sometimes I will listen to audio lectures online such as from the MIT website. It doesn't report but a couple of seconds here.

I know this is due to the program reporting that I am inactive so that it doesn't record time I may spend away from the computer, however is there not a way to have it record time regardless in case I want to capture the time that I spend doing these things also?
