I just upgraded the firmware on my HD-PVR from 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?

Or for some reason the v4l2-ctl lines aren't having an effect when run inside the script. Is there any other point when a recording starts, besides the channel change script, to run a script? If so, and if there is another script point, at least I could have a workaround to adjust the picture adequately until I found a real fix.</div>
