[mythtv-users] hdpvr latest firmware color saturation issue question

[Mitch Capper]

Two reasons it may not work from the script are if the path does not
include v4l2-ctl (try using the abs path to it) or if its because you
are changing the channel right before using it maybe its busy.  Try
using it before changing the channel.
