 Summary of the bug:
 Using the Hauppauge HD-PVR does not work anymore. Used to work on Ubuntu
 14.04, does not at Ubuntu 16.04 nor at Arch Linux. A self-compiled avplay
 does the job. If it helps: open broadcast studio (obs-studio) cannot open
 the device-file either, same error as 'ffplay /dev/video0'

 I used Arch Linux for the output below:

 Using the device with 'cat /dev/video0 > test.mp4' works perfectly well.
 Even 'gst-play-1.0 /dev/video0' works. Output of v4l2-ctl:
