Do you have a TV-out cable on your Matrox? And is it a G400?

The pin assignment fot the TV-out cable, what Matrox describes in their 
web-forum, may be correct for Matrox. But after using such an adapter I also 
had the problem that loading the DVB drivers took very long. My solution was 
to cut the connection between pin 15 and 12. After this it was working 
without the delay.
