[mythtv-users] PVR-150 MCE captures nothing but static

Apparently this issue has something to do with the "tuner" input.

Composite video worked just fine.

Unfortunately, my setup does not include a tower case in the living room; the DVR is to be placed in the office, about 100 feet from the TV and set-top box.  Easy and cheap enough to pull off with coaxial cable...not so much with component video & audio.

Any idea why the tuner input is giving me static?  I can get another set-top box fro m the cable company, but this issue irks me.

I installed the card and myth with only a little difficulty using Jarod's guide (substituting repos as I am using CentOS and not Fedora Core).  Ivtv seems to recognize the card at /dev/video0, and I can apparently see what's going on with the card by using mplayer (mplayer -vo x11 /dev/video0).  Unfortunately what's going on is nothing but static.

Right now I am just trying to view a DVD, so I have the coaxial cable from the DVD player going into the connector on the card.

I am using input 0 ("Tuner")...

[root at rockstar etc]# ivtvctl -d /dev/video0 -n
ioctl: VIDIOC_ENUMINPUT
        Input   : 0
        Name    : Tuner
        Type    : 0x00000001
        Audioset: 0x00000003
         Tuner   : 0x00000000
        Standard: 0x0000000000003000 ( NTSC )
        Status  : 0

...and I have tried changing the channels with ivtv-tune:

[root at rockstar etc]# ivtv-tune -c 3 -d /dev/video0
/dev/video0: 61.250 MHz

What gives?  I have tried googling for this problem but mostly I find either people asking on various forums (with no responses) or the standard advice--"Try changing the channel."  Any ideas?

Regards,
Pete
