Hartmut is trying to establish a means in telling the difference between the frontends installed on the multiple devices in a single given system. For instance, I have a mythtv backend server with five PCI cards inside... each of which use the LG DT3303 ATSC demod. Given that each of these frontends identify themselves as an LG Electronics DT 3303, how does the user know which frontend is associated to the FusionHDTV 5 Gold? Which one is the AirStar HD5000? Which one is the FusionHDTV5 USB Gold? Does this explain the question any better?
I think you got a lot confused .. manu _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
