Hi Sirs: I am working on the Dvico HDTV7 Dual Express TV tuner card under Linux environment with kernel (2.6.26). When I check the snr value and signal status about every 10 seconds, it works fine in first few hours, but it will stop after about 12 - 24 hours. I found out if i check the snr and signal status every second. It will stop after 5 hours. If I check the snr and siganl status every time it read PES, it will stop in few minutes. And it will show the message==> value too large for defined data type, Read -1 byte from DVR. Do you think it because the driver is not compatible with my Desktop? Or I shouldnt check the snr value? Thank you so much Tu Tu Yu tutuyu@xxxxxxx _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
