Installed 0.27 on ubuntu 12.04 and got the problem mentioned above. I experimented with different version of MythTV and Ubuntu/Debian for a couple of month. Every time I compiled mythtv from the source. And the result was, as i said, _LMSC displayed at the bottom of the screen. And when i reinstalled 0.24, TLMS is back again.

I'm afraid I'm not sure I have much more I can suggest. I would probably recommend doing (on latest fixes/0.27) a delete all Capture Cards / Video Sources / Input Connections (on all hosts) (within mythtv-setup) then re-add everything back in order - but not because I have any particular insight into the issue but because it is probably just a good troubleshooting step when upgrading from 0.24 and IIRC it has helped with similar tuner lock issues in the past.

Or else start from scratch with a clean empty database to eliminate any legacy database issues.

Also maybe run optimize_mythdb.pl to check the database tables http://www.mythtv.org/wiki/Optimize_mythdb.pl

The suggestion was to cover the possibility that your recording folder(s) were different to your livetv folder(s). Is your recordings folder the same as your livetv folder (in your storage group setup)? I don't recall what the default folder locations are.

See http://www.mythtv.org/wiki/MySQL_Time_Zone_Tables for details.
