I already tried a more recent firmware and driver, so I am now working with firmware v4.95.0 and changeset 71dec186cdae of the v4l-dvb repository. My system is running on a 2.6.28-15-generic #49-Ubuntu SMP kernel. What do these error messages mean? What meaning do the numbers have? Could it be that my hardware is broken? It has now been working for over a year now without major problems (and even better than on Windows, thanks to v4l-dvb ;-)) Thanks in advantage, Roland Hieber _______________________________________________ linux-dvb users mailing list For V4L/DVB development, please use instead linux-media@vger.kernel.org linux-dvb@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
