Ok, now I can get recording working when I set the "quick tune" option to "always". When I change this setting, I get the following results :

  • never ==> both live tv and recording fail
  • always ==> both live tv and recording work
  • live tv only ==> live tv works and recording fails

There seems to be something wrong in this multiplex, or in myth, or both. I don't know if this is relevant, but when I use the "scan" tool on this multiplex, it attempts to tune to "-10" and outputs some errors about this (and in dmesg too: "DVB: frontend 0 frequency 4294967286 out of range (177000000..858000000)").

Please attach a dump of the channelscan tables (you will need to update to trunk). It appears it's not getting all the tuning info.

I would suspect missing networkid or transportid with quick_tune set to live-tv
