The PAL pvr500MCE is successfully installed using ivtv-0.3.6d version.
The second tuner is unable to tune the frequency while first tuner is very
easy to tune. I have compared the ivtvctl -a for /dev/video0 and
/dev/video1.
Only the the Bus info. video0 is 0 while video1 is 1
ioctl VIDIOC_QUERYCAP ok
Driver name : ivtv
Card type : WinTV PVR 150
Bus info : 0
Driver version: 774
Capabilities : 0x01070011
I dump the register output, cx25840ctl -d /dev/video1 -l > v1.dump . on
video0 and video1. and make the diff

It seems that some AGC register values are different on the two tuners.
May be values are runing change value. How to solve ?. Would we direcly
set the register value and make them same. I need to make both tuner. Any
setting can solve it ?
