Having a problem where changing channels with a PVR-150 tuner doesn't actually
change the channel.
Issuing a 'ivtvctl -d /dev/video0 -a | grep Freq' does show the frequency
changing, but doing a capture it is always on the same channel. Changing
channel with either MythTV or 'ivtv-tune -c' yields the same result. Video and
sound is captured fine, just always the same channel no matter what I try.
Everything appears to be initializing without errors:

Trying to change channels gives the following:
Dec 24 18:29:12 mythtv kernel: ivtv0 ioctl: v4l2 ioctl 0x402c5639
Dec 24 18:29:12 mythtv kernel: ivtv0 ioctl: VIDIOC_S_FREQUENCY

Dec 24 18:29:12 mythtv kernel: ivtv0 ioctl: VIDIOC_G_TUNER
Again, 'ivtvctl -d /dev/video0 -a' shows the frequency change, but 'cat
/dev/video0 > test.mpg' still records the same channel.
Some info:
Distro: Slackware 11.0
Kernel: 2.4.33.3
ivtv: Compiled from source - originally 0.4.8, upgraded to 0.4.9 with no change
lspci -v results:

MPEG-2 Encoder (rev 01)
Subsystem: Hauppauge computer works Inc. WinTV PVR 150
Flags: bus master, medium devsel, latency 64, IRQ 5

Been searching everywhere, and haven't been able to find a fix for this.
Thanks for any help anyone can give, and hope y'all are having a Merry
Christmas.
