Upon closer inspection I noticed mplayer was indeed still running in the background and killing it solved the problem entirely. I found that after tuning to different channels a few times mplayer becomes sluggish and starts dropping frames, and when I then close the mplayer window, the process remains in the background. So I guess this is an issue with mplayer, thanks for the clue :)
