Several people reported problems with the saturation of the PVR150/500
cards. Please try the following command:
ivtvctl -g reg=0x401,val=0xe0
You have to be root to run this command and you may have to pass the
-d /dev/videoX option if your card is not /dev/video0. You also have to
run that command twice for the PVR500, once for each unit.
Chroma was handled badly for the tuner and composite inputs, this should
fix it. The bits that are set by this command used to be present in old
ivtv releases but they were dropped for no apparent reason during a
rewrite of the cx25840 module somewhere around 0.3.2.
Please test and report whether this fixes the saturation issues.
