[mythtv-users] Different Audio/visual effects on two capture cards

I recently made two upgrades to my PVR and I am trying
to determine how to fix the two problems that have
recently generated as a result.
My system consisted of a PVR350 and mythtv .18.1.  I
recently bought a pvr150 mce and upgraded to myth .19.
 Everything seems to be working correctly and its
great to have two tuners however I have noticed a mild
difference in picture quality with the new pvr150.  It
seems the brightness is very high and the hue is
slightly off.  Sometimes the picutre looks almost like
a black and white tv.  The other issue is that the
pvr350 volume is very low in comparison to the 150.
     I tried playing with the settings via the ivtvctl
program but that seems to get reset as soon as I
change channels or exit myth and re-enter.

Any help on how to overcome this problem would be
appreciated.  I  couldn't find a setting that set this
permanently.

Below is the out put from my ivtvctl -Y:

#PVR150
# ivtvctl -Y -d /dev/video0
ioctl: VIDIOC_QUERYCTRL
Brightness = 383 #Why is this so high?  I thought this
was suppose to be from 0-255?
Contrast = 63
Saturation = 63
Hue = 0
Volume = 59392
Mute = 0

#PVR350
# ivtvctl -Y -d /dev/video1
ioctl: VIDIOC_QUERYCTRL
Brightness = 127
Contrast = 63
Saturation = 63
Hue = 0
Volume = 59605
Mute = 0
