Just a note: both non-working cards uses a tda10023 chip, so I think it should a good start pointing... -- Christian Lyra PoP-PR/RNP _______________________________________________ linux-dvb users mailing list For V4L/DVB development, please use instead linux-media@xxxxxxxxxxxxxxx linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
