Hello again, I've been trying to make the OnAir creator work. So far it hasn't been easy but I'm making some progress. Pvrusb2 told me in the log file that a firmware file was missing, so I went looking for it by name. After a convoluted procedure extracting windows-centric files and renaming the proper one to v4l-cx2341x-enc.fw I put it in /lib/modules and did away with the missing firware message. Dvbusb2 seems to recognize the device ok. In fact it seems to create /dev/dvb/adapter0/demux0 /dev/dvb/adapter0/dvr0 /dev/dvb/adapter0/frontend0 /dev/dvb/adapter0/net0 And I also see /dev/video0 But what do those devices represent? Is /dev/video0 the analog tuner? is /dev/dvb/adapter0/dvr0 the digital tuner? What are the others? I have been trying to configure mythtv but have no idea what to tell it about this device. The mythtv docs say that if you have a card with 2 tuners, define it as a DVB. But, mythtv-setup identifies it correcly (by name) as an analog card /dev/video0, if I set it up as a DVB it claims it is a DVICO or Air2PC or... It does not seem to know about the /dev/dvb devices. Do I need to configure the OnAir Creator as 1 or 2 devices? Can someone tell me a quick and easy way to test the device? maybe with mplayer? I have an analog camera connected to the composite input, so even if I don't get any channels with the rabbit ears and loop antenna, that should work as a test. I have posted the higher level questions to the mythtv mailing list, but no answers yet. Any hints would be welcome.
