[mythtv-users] Composite issues.....

In the past I've had one of my composites setup to record from my
camcorder. Since updating to .20, switching backend machines, etc, it's
no longer configured. I have a PVR350, 250, and 150. I'm using ivtvctl
to figure out what port I need to assign the composite to. 

I run the following commands for /dev/video0:
/usr/bin/ivtvctl -d /dev/video0;ivtvctl -p 1;cat /dev/video0 > video0_p1.mpg
/usr/bin/ivtvctl -d /dev/video0;ivtvctl -p 2;cat /dev/video0 > video0_p2.mpg

I run the following commands for /dev/video1:
/usr/bin/ivtvctl -d /dev/video1;ivtvctl -p 1;cat /dev/video1 > video1_p1.mpg
/usr/bin/ivtvctl -d /dev/video1;ivtvctl -p 2;cat /dev/video1 > video1_p2.mpg

I run the following commands for /dev/video2:
/usr/bin/ivtvctl -d /dev/video2;ivtvctl -p 1;cat /dev/video2 > video2_p1.mpg
/usr/bin/ivtvctl -d /dev/video2;ivtvctl -p 2;cat /dev/video2 > video2_p2.mpg

If I have the camcorder plugged into the SVideo on the PVR350 I find
that this one works:
/usr/bin/ivtvctl -d /dev/video0;ivtvctl -p 1;cat /dev/video0 > video0_p1.mpg

On the 250 and 150 it doesn't matter what input I cat from, it always
shows me what appears to be the tuner. I'd really like to use the 250 or
150's inputs since they have straight composite rather than SVideo.

Anyone have any suggestions on how to resolve this?
