My brothers mythTV setup currently consists of one MBE with 2x DVB-T tuners in. Both tuners are from identical Medion PCs and report the following from dmesg when booted... mythtv-user@mythBE1:~$ dmesg | grep -i dvb [ 62.626167] saa7134[0] Board has DVB-T [ 63.405856] saa7134[1] Board has DVB-T [ 63.933725] DVB: registering new adapter (saa7134[0]) [ 63.933729] DVB: registering frontend 0 (Philips TDA10046H DVB-T)... [ 66.281192] DVB: registering new adapter (saa7134[1]) [ 66.281197] DVB: registering frontend 1 (Philips TDA10046H DVB-T)... My brother lives in an area that suffers very short power-outages if there is a storm or whatever and I have noticed that after such an event, he loses the ability to record TV from both tuners and generally only one will work. I am never sure if it is always the same tuner that as busted since I don't know which is dvb0 or dvb1 at any point in time. To correct this, I remote into the server and issue a 'halt', get him to unplug it from the wall then press the power button on the front of the machine, re-plug it into the wall and boot up the server. Then both tuners are working fine. I understand the best way around this might be a UPS, but I don't have the ability to get one at the moment, though it will be his next purchase. In the meantime I was wandering if anyone had any suggestions for getting around this problem. For my tuners that used to suffer a similar problem (but which are different tuners) I had to add some lines to rc.local to remove the dvb modules and then re-insert them and this seemed to work. There are a number of similar posts in the archives like this. I have tried this for the saa7134 modules but to no avail.
