I've connected an Antennas Direct ClearStream 2V (http://www.antennasdirect.com/store/ClearStream-2V-UHF-VHF-Indoor-Outdoor-DTV-Antenna-With-Mount.html) antenna to the Hauppauge WinTV-HVR-950Q atsc tuner. After adding the <code>us_ATSC_center_frequencies_8VSB</code> DVB network, the "Muxes awaiting initial scan" failed to start counting down. Here's how I fixed it.
<code>dmesg</code> reported the following:
[ 3931.964710] xc5000: waiting for firmware upload (dvb-fe-xc5000c-4.1.30.7.fw)...
[ 3931.970217] xc5000: Upload failed. (file not found?)
I downloaded the 950Q firmware from
http://www.kernellabs.com/firmware/xc5000/. You'll need to determine where to place the firmware; Ubuntu uses <code>/lib/firmware/</code>. When I copied the firmware, I checked <code>dmesg</code> and saw
[ 4791.147048] xc5000: firmware read 16497 bytes.
[ 4791.147049] xc5000: firmware uploading...
[ 4794.976020] xc5000: firmware upload complete...
Restarting Tvheadend found 68 muxes, and "Muxes awaiting initial scan" started counting down from 68. All fixed!
