MythTV 0.20
Ivtv 0.8.1
Kernel 2.6.18.1
I found a good thread on this:

Where Mike suggested:
ivtvctl -u 0x3000
ivtvctl -p 6
ivtvctl -f width=720,height=480
dd if=/dev/video0 of=/tmp/myvideo.mpg
Problem is with ivtv 0.8.1 none of these switches exist anymore. Or at
least I get usage with them.
Ivtvctl -h
Usage:
-d, --device <dev> use device <dev> instead of /dev/video0
-h, --help display this help message
-K, --passthrough <mode>
set passthrough mode: 1 = on, 0 = off
[IVTV_IOC_PASSTHROUGH]
-W, --get-vbi-passthrough
query the current VBI passthrough mode
[IVTV_IOC_G_VBI_PASSTHROUGH]
-w, --set-vbi-passthrough=<mode>
set the current VBI passthrough mode to <mode>
[IVTV_IOC_S_VBI_PASSTHROUGH]
<mode> is a comma separated list of:
none: no passthrough
cc: closed caption
wss: widescreen signal
vps: vps
--get-yuv-mode display the current yuv mode
--set-yuv-mode [param],[param]
set the current yuv mode
param:
mode =<#> yuv_mode 0=interlaced,1=progressive,2=auto
threshold =<#> if src_hight <= threshold treat as progressive
--reset-ir reset the infrared receiver [VIDIOC_INT_RESET]
--version shows the version number of this utility.
It should match the driver version.

<chip> is one of: saa711x, saa7127, saa717x, cx2584x,
cx2341x
-r, --set-register chip=<chip>,reg=<reg>,val=<val>
set register [VIDIOC_INT_S_REGISTER]

Any suggestions?
