After 6 hours I must say that my VDR did not bring yet back the error. So far otherwise always. I want to hope that it functions now. :) In the LOG comes however repeatedly: Jan 3 18:15:43 cat vdr[16675]: ERROR: frontend 0 lost lock Jan 3 18:15:43 cat vdr[16675]: frontend 0 regained lock Jan 3 18:16:03 cat vdr[16675]: ERROR: frontend 0 lost lock Jan 3 18:16:03 cat vdr[16675]: frontend 0 regained lock Jan 3 18:16:25 cat vdr[16675]: ERROR: frontend 0 lost lock Jan 3 18:16:26 cat vdr[16675]: frontend 0 regained lock Jan 3 18:16:45 cat vdr[16675]: ERROR: frontend 0 lost lock Jan 3 18:16:45 cat vdr[16675]: frontend 0 regained lock Jan 3 18:17:06 cat vdr[16675]: ERROR: frontend 0 lost lock Jan 3 18:17:06 cat vdr[16675]: frontend 0 regained lock My primary frontend is device 3.
