The card always outputs native PAL or NTSC, etc. timing.  The "modes"
provided by xrandr just define the desktop size that is downscaled to
the native tv timing.  Changing the mode doesn't change the timing,
only, the desktop size and scaling factor.  To adjust the tv settings,
use xrandr, e.g.,
xrandr --output DIN --set "tv standard" pal
To see all the properties for your connectors, run:
xrandr --verbose

Adjustable over/underscan support has not been implemented with tv-out
at the moment.
