Hi All,<br>
<br>
Ubuntu 12.04 and MythTV 0.25.1<br>
<br>
I have a hdpvr that works fine with the exception of color balance. As documented multiple places, the device can be controlled with 'v4l2-ctl' and this issue can be fixed.<br>
<br>
So I have a bash script to change the settings using this approach that's called by my channel change script.<br>
<br>
Unfortunately, the script does not seem to run when channel changing, though it does when I run from command line.<br>
<br>
I suspect this is a permission problem, so I added mythtv (the user that runs the backend) to the video group on this machine and verified that group permissions on /dev/video1 (pvr-150 on video0) allow both reading and writing.<br>
<br>
Still there seems to be no change to the device. Also, I'm not sure where to find stderr output from the channel change script. It does not seem to appear in the mythbackend log.<br>
<br>
Any pointers to solutions to what must be a common problem?<br>

Perhaps you're running it too early--before MythTV sets it device settings? Try putting a sleep in the channel change script before the color-fix script is run.<br>
<br>
Also, I think there's a fix for the "wrong colors with new HD-PVR firmware versions" available (in new kernels or something?). Might want to just fix the issue, instead of working around it.<br>
<br>
Mike<br>
