[QUOTE="mm1352000, post: 1188277, member: 82144"] The unknown error stems from this: [2016-06-20 16:57:14,615] [Log ] [26 ] [INFO ] - dvb: RunGraph returns: 0x8007001F That comes direct from the tuner driver. Essentially what's happening is the following... [LIST] [*]you attempt to tune a channel [*]TV Server recognises both tuners are free [*]TV Server tunes with the first tuner, but receives the above error when asking the tuner to start the stream [*]TV Server tries again with the second tuner, and hits the same error [*]TV Server gives up and reports the problem to you as "unknown error" [/LIST] It's "unknown error" because the error code - 0x8007001F - supplied by the tuner driver simply means "general failure" (ERROR_GEN_FAILURE). It's totally unhelpful, and hence TV Server cannot provide a more useful error message. Actually the thing that interests me the most in your log files is what happened on the evening of the 19th. You had a failed attempt to tune BBC FOUR (both tuners fail): [2016-06-19 21:55:06,179] [Log ] [23 ] [INFO ] - card: Tune on card 3 to subchannel BBC FOUR [2016-06-19 21:55:06,179] [Log ] [23 ] [DEBUG] - card: user: LivingRoomHTPC:3:-1 tune DVBT:tv: BBC FOUR Freq:498000 ONID:9018 TSID:4163 SID:4544 PMT:0x190 FTA:True LCN:9 BandWidth:8 [2016-06-19 21:55:06,434] [Log ] [23 ] [INFO ] - dvb: RunGraph returns: 0x8007001F [2016-06-19 21:55:06,497] [Log ] [23 ] [INFO ] - card: Tune on card 4 to subchannel BBC FOUR [2016-06-19 21:55:06,497] [Log ] [23 ] [DEBUG] - card: user: LivingRoomHTPC:4:-1 tune DVBT:tv: BBC FOUR Freq:498000 ONID:9018 TSID:4163 SID:4544 PMT:0x190 FTA:True LCN:9 BandWidth:8 [2016-06-19 21:55:06,747] [Log ] [23 ] [INFO ] - dvb: RunGraph returns: 0x8007001F Approximately half an hour later, without any TV Server activity (restarting, tuner reloading etc. - nothing, zero, zilch, nada!) you're suddenly able to tune Channel 4+1, BBC ONE and ITV2: [2016-06-19 22:29:30,553] [Log ] [5 ] [INFO ] - card: Tune on card 3 to subchannel Channel 4+1 [2016-06-19 22:29:30,553] [Log ] [5 ] [DEBUG] - card: user: LivingRoomHTPC:3:-1 tune DVBT:tv: Channel 4+1 Freq:522000 ONID:9018 TSID:8206 SID:8452 PMT:0x4B0 FTA:True LCN:13 BandWidth:8 [2016-06-19 22:29:30,600] [Log ] [5 ] [INFO ] - dvb: RunGraph [2016-06-19 22:29:33,446] [Log ] [5 ] [INFO ] - dvb: LockInOnSignal ok [2016-06-19 22:29:45,028] [Log ] [5 ] [INFO ] - card: Tune on card 3 to subchannel BBC ONE South [2016-06-19 22:29:45,028] [Log ] [5 ] [DEBUG] - card: user: LivingRoomHTPC:3:0 tune DVBT:tv: BBC ONE South Freq:498000 ONID:9018 TSID:4163 SID:4163 PMT:0x64 FTA:True LCN:1 BandWidth:8 [2016-06-19 22:29:45,439] [Log ] [5 ] [INFO ] - RunGraph [2016-06-19 22:29:45,454] [Log ] [5 ] [INFO ] - dvb: LockInOnSignal ok [2016-06-19 22:30:27,554] [Log ] [26 ] [INFO ] - card: Tune on card 3 to subchannel ITV2 [2016-06-19 22:30:27,554] [Log ] [26 ] [DEBUG] - card: user: LivingRoomHTPC:3:0 tune DVBT:tv: ITV2 Freq:522000 ONID:9018 TSID:8206 SID:8325 PMT:0x708 FTA:True LCN:6 BandWidth:8 [2016-06-19 22:30:27,946] [Log ] [26 ] [INFO ] - RunGraph [2016-06-19 22:30:27,979] [Log ] [26 ] [INFO ] - dvb: LockInOnSignal ok You stop time-shifting: [2016-06-19 22:32:05,075] [Log ] [26 ] [INFO ] - card Nova-DT DVB-T Tuner (Dev1 Path0) : StopTimeShifting user:LivingRoomHTPC sub:0 Not 30 seconds later, you try to start viewing ITV2 again: [2016-06-19 22:32:23,347] [Log ] [33 ] [INFO ] - card: Tune on card 3 to subchannel ITV2 [2016-06-19 22:32:23,347] [Log ] [33 ] [DEBUG] - card: user: LivingRoomHTPC:3:-1 tune DVBT:tv: ITV2 Freq:522000 ONID:9018 TSID:8206 SID:8325 PMT:0x708 FTA:True LCN:6 BandWidth:8 [2016-06-19 22:32:23,591] [Log ] [33 ] [INFO ] - dvb: RunGraph returns: 0x8007001F ...and the error is back! :eek: ...and that error continues through the rest of the log file.
