Try to check the Specification of the MBD from the Technical Product Specification and the Tuner card Technical Product Specification if the system requirement is validated. Other than this, i dont have any suggestion. Hopefully, someone else can give us some light on this if they already have the answer.
I had the updated chipset and graphics driver...There is a newer bios update, I tried it, but still no good. It's really weird, like I said, I can record the qam stations and play them back, and i can watch them live via an extender, I just can't watch them live through the DVI out, the analog stations play fine, I only have issue with qam. I don't have an hdmi tv to check that, I guess it's possible it may work. I'm pretty new to all of this, so it could even be something simple.
