What is the result of connecting a single link (DVI-D) video source to a dual link monitor?

I was trying to hookup the mini to a Television with svideo/composite
input.  The minidisplayport to svideo/composite doesn't work.  The
minidisplayport to VGA with a simple VGA to svideo/composite won't work
because the VGA doesn't have an analog signal in it.  To get svideo out of
the VGA, I needed use a (digital) VGA to svideo converter.

For my VGA display I used for debugging, it just worked :-)

I was kinda disappointed that a $5 VGA to svideo adapter didn't work for the
TV.  The converter was $30. :-P
