[QUOTE="gibman, post: 917476, member: 25430"] what it says is: [B] res id blocking=31, state=TuneCancelled[/B] here u can see see why the tuner reservation failed. it's because of previous reservation with id 31 not releasing the lock[B]. [/B]It's last known state was 'TuneCancelled'. in order to find the culprit tune reservation in the logs, look in tv.bak file for 'CardReservationBase.RequestCardTuneReservation: placed reservation with id=31' [CODE] 2012-09-18 22:58:40.433566 [DVB EPG timer(4)]: CardReservationBase.RequestCardTuneReservation: placed reservation with id=31, tuningdetails=DVBS:radio:BSkyB Kismat Freq:12523000 ONID:2 TSID:2612 SID:9566 PMT:0x141 FTA:True LCN:470 SymbolRate:27500 Modulation:ModNotSet Polarisation:LinearV InnerFecRate:Rate2_3 DisEqc:None band:Universal Pilot:NotSet RollOff:NotSet [/CODE] somehow this thread stops here ??
