Start mythfrontend with the "NO_XV=1" environment variable set (NO_XV=1 
mythfrontend). This will ensure that mythfrontend doesn't try to use 
XVideo (Which is what's causing the blue screen - XVideo chromakeys the 
video onto that blue surface on the graphics card itself, which VNC 
can't get to as it's not in the framebuffer).
