Thanks for the pointer. At this point it appears that now I can get
video via the first tuner on the PVR-500. This started working after a
reboot of the system. Still no video from the second tuner on the
PVR-500 card.
I compared the results of the ivtvctl -a command for both /dev/video1
and /dev/video2 (/dev/video0 is the PVR-350 in my system). I noted the
following differences, the capabilities lines are different and I see
odd entries in Brightness, contrast, etc. Trying to find a way to
change those setting now.
I don't have a windows system to try this card in so I need to sort out
if I have a hardware problem or just a configuration problem. Hopefully
it is just the default settings provided by the driver are not correct
for the second tuner.
/dev/video1
Capabilities : 0x01070011
Video standard = 0x00003000
ioctl: VIDIOC_QUERYCTRL
Brightness = 128
Contrast = 64
Saturation = 64
Hue = 0
Volume = 60928
Mute = 0
/dev/video2
Capabilities : 0x01030011
Video standard = 0x00003000
ioctl: VIDIOC_QUERYCTRL
Brightness = 0
Contrast = -182619467
Saturation = -2146937321
Hue = -172077056
Volume = 0
Mute = 0
