I recently gave my sister my first HTPC setup. She purchased a USB tuner to add to he Diamond 750 PCIe tuner installed. The QAM playback in WMC is slow and glitchy especially with HD channels. Any suggestions? I suspect the USB tuner may be at fault. Is the a way to set the PCIe tuner as the default or might something else be a possible solution?
