I'm not clear on what you want to do... do you want to: (1) have a 
remote display mirror your TV (i.e., some display on a laptop showing 
exactly what is simultaneously on your TV screen), or do you want (2) 
to be able to run mythfrontend and have it show up on your laptop 
instead of the TV?

If (1), you need a VNC server on the Linux side that is capable of using 
a 'live' X11 display.  Try this:  http://www.karlrunge.com/x11vnc/

If (2), you need to install Cygwin and set up an X server, as several 
people have already indicated.

Good luck,
