all the video outputs look fine.  i tried switching the input to tuner:

#ivtvctl -d /dev/video1 -p=4
ioctl: VIDIOC_S_INPUT
Input set to 0

which looks to me like it's leaving the input at "Composite 0"

a modification, now that i look at it. when i first load the ivtv 
module, "ivtvctl -P -d /dev/video1" says that the tuner input (4) is 
selected.  however, ptune still gives errors when attempting to change 
channels, and once i try to select a new input it goes right back to 
"Input set to 0"

super weird.
