I'm seeing the same thing on a Biostar TA690G mainboard, which uses the same chipset. It works fine on my desktop machine though (VIA K8T800PRO chipset; ASUS A8V Deluxe) and on my ASUS Eee (can't remember off-hand what chipset that uses, an Intel one of some description IIRC). Had some strange signal issues with the Nova-TD-Stick too - Tuner 0 worked fine, but Tuner 1 failed to lock onto the mux that carries FilmFour. Putting a 6dB attenuator inline fixed that nicely -- seems the low-noise amplifier in the Microtune chip sets its level based on an average of the whole band it's tuned to. Lots of strong signals = low amplification = not much signal strength going into the DiBcom decoder/demux chip. Weaken some of the strong signals, and it's fine. Most peculiar. -- Phil. | (\_/) This is Bunny.
