#Mythubnu autoexpire upgrade

There a many things that can cause tuner error, unfortunately it is a process of elimination. It would help if you can advise on the mythtv version (in a terminal session do mythbackend -version) and paste the output.Īlso what are the types of tuners, from your console output you seem to have 4 tuners (adapter0. I then investigated access of /dev/dvb as below, looks ok to me but I'm running out of ideas.

Same error in frontend about tuners busy.

I have again removed all capture cards ('Delete all capture cards' option) and setup just one (same as previously, mostly default with 1000ms signal timeout, 3000ms tunning timeout, 3 multiplexes, wait for SEQ start header enabled, Open DVB card on demand disabled, Use DVB card for active EIT scan disabled (until I can get LiveTV working), 1ms DVB tunning delay). livetv directory seems to have correct permissions (including write permissions) for mythtv group (which my user is part of). Going to Tuner Status from System Information in frontend it show 'Tuner 1 has an error' and 'Tuner 1 has an error]' (along with other 2,3,etc). In the frontend interface I can see and watch previous recording but am unable to use the tuners to 'Watch TV' as it returns a 'All tuner are currently busy' alert. It found the required channels (so I presume tuners are working as expected given they can find channel locks). I setup the new capture card info in the backend then re-added and used the tuner to scan for channels.

After a major system upgrade (most hardware replaced) I installed Xubuntu and mythtv and resorted my mythtv database.
