PC-HD300 can not get DVB channel scan to work.
 
We have a PC-HD300 card and I am trying to get the dvb part of the card to work. We can successfully record using the V4L from unencoded analog channels. We can also record both digital and hd channels from my settop box connected via s-video or coax. When I try to go direct from the ASI source using DVB I am having issues. We have the modules loaded properly ( /dev/dvb/adapter0/ demux0 dvr0 frontend0 net0.) We have loaded the proper firmware for my card using hotplug (dvb-fe-or51132-qam.fw dvb-fe-or51132-vsb.fw dvb-fe-or51211.fw).
Following instructions from such sites as http://www.penlug.org/twiki/bin/view...lTelevisionDVB , and using various documentation from mythtv.org etc.... We have been unsuccessful in our attempts to view and/or record anything using the dvb features of this card. We know the cable company uses QAM 256 but have had no success in finding or scanning any channels. When running atscscan (**/atsc/ us-Cable-EIA-542-HRC-center-frequencies-QAM256, us-Cable-EIA-542-IRC-center_frequencies-QAM256, us-Cable-HRC-center-frequencies-QAM256 us-Cable-IRC-center-frequencies-QAM256, us-Cable-Standard-center-frequencies-QAM256) I only get tuning failed (some timeouts but I am unsure if that means anything). I have the frequencies of each QAM provided by the cable company. I know I am probably missing something simple but I am looking for some feedback on how to troubleshoot this issue.
