This tells you
   * the connection to the TV has been detected
   * there are two preferred modes (shown by the '+')
   * the current mode is 800x600 (shown by the '*')

There is no need to do this because the cable connection is detected,
but I do not think it does any harm. I have to do it on one machine
because I'm told 'S-video disconnected ....'.

'--crtc 1' isn't really required.

Forget about this for the moment. I should have been clearer and
explained I use xvattr to send video to the TV with vlc. It is of no
consequence if nothing appears on the TV screen in the first place). The
command for you to use to see a portion of your computer screen on the
TV (because the TV is detected) is

   xrandr --output TV1  --mode 800x600 (or --mode 848x480 etc)

It might be useful for us to see the outputs of 'xrandr --verbose' and
'lspci' for the video card.
