[mythtv-users] IVTV issues (video scrambled looking)

[Mickey Chandler]

I just finished moving and that means a change in inputs.

Before I moved, I had things set up for capturing from a D-10 DirecTV 
box.  Now, we're simplifying things a bit and going with extended 
basic cable.  That means that I should be able to plug the coax into 
my PVR-250 and go.  I was expecting this to be pretty easy.  But, it's not.

The audio is there, but video is not.  Video for any available 
channel (2 - 64) looks like it's a scrambled channel.  Plugging the 
coax directly into the television results in a proper picture for 
those channels, so I know the signal coming in is good.

The box is running FC4 with the latest kernel (2.6.16-1.2111_FC4), 
and IVTV 0.6.2.  Here's the IVTV stuff that usually gets requested.

If anyone has any hints as to what simple thing I'm probably missing 
here, I'd be most appreciative.
