Other than the fact that sound and video work properly when using dd to
pipe /dev/video0 directly to /dev/video16 and the fact that MythTV gives
an error message when I select the "Watch TV" option, I might think that
mis-plugging my cables is the problem. However, if I boot up my MythTV box
and exit Myth, then run the following (from memory, may be typos), I get
perfect sound and video:

pkill twm
ivtvctl -p4
ivtvctl -u 0x3000
ivtvfbctl /dev/fb1 -noglobalalpha -localalpha
dd if=/dev/video0 of=/dev/video16 bs=64k

At this point, my TV starts displaying the video and playing the audio
from channel 3.

To me, this says that the cables are properly plugged in and the ivtv
driver is doing what it's supposed to. The problem arises when I try to
watch (or record) TV in MythTV.
