If not, it sounds like a hardware problem.. budget cards are sometimes just /too/ budget for some cams... Its pretty much pot luck whether a given brand/type of cam works with them. I'v found the technotrend budget boards are more reliable for CAMs. I /think/ the "full featured" cards have a proper cam interface chip on them, so they're far more compatable (altho obviously they're more expensive). _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
