I just upgrade the firmware on my HD-PVR from a version 0x12 May 7, 2009 to the latest from the Hauppauge web site, 0x17 July 27, 2011. Now all recordings from the HD-PVR are way oversaturated. Catting /dev/video0 and playing the file with vlc yields the same result. According to v4l2-ctl -l, the settings are all at defaults. Any ideas what the problem could be?
