Cheers for the info mate; didn't have the balls to try it without on official ok.
The main reason for asking was that I was close to running out of molex plugs on my psu, especially with considering running with 2 of the tbs6284 cards.
Hope you get your gpu sorted. Might have to bite the bullet and get a second card. Currently running 3 dual tuners, but not happy with the quality, hence upgrading to the quad. Been testing the card and am very happy with the results to date; much better quality (less artifices) and quicker channel ...
Just ordered one of your quad tuners. I'm currently using W7 media centre 64 bit with 4 extenders running off of the main pc; has anyone tried using 2 quad tuners in one machine, as ideally 6 tuners regularly get used in my house?
