[mythtv-users] MythTV 0.20.2: frontend can't lock DVB-S - strange behaviour!

Hello All,

  I have Fedora Core 6 and MythTV 0.20.2 set up since quite a few
  months. I'm watching DVB-S using TT S-1401 card and it was working
  just great when I had only one antenna.

  Now I decided to try with another satellite. Therefore I bought a
  new antenna and a DiSEqc. Everything was connected and HW set up
  went fine. I first tried with Kaffeine, and it worked great for
  both satellites - I could watch any channel, DiSEqc switching also
  worked good.

  But I seem to have a mysterious problem with my MythTV. At first I
  went to mythtvsetup, reconfigured my DVB-S card to have a "Switch"
  with 2 inputs. Then I configured my Video Sources so that each input
  gets it's own source. Then I went to Channel Search and made a
  search on all transpoders on the second input. Strangely, it found
  some channels from the first input and some other channels from the
  second. So the output was 'mixed'...
  Ok, no problem with me. I decided to see what I got. I started
  mythfrontend and tried to watch LiveTV. All the old channels worked
  just fine. But the new ones got 'No Lock'.

  I removed DiSEqc, connected the new antenna directly to the DVB-S
  card and repeated the Channel Search. This time it found lots of
  channels (seem to be the right ones). But my frontend still shows
  'No Lock' despite all my efforts. OSD shows (L_s) most of the time,
  although sometimes it's just (l__).

  Strangely, during channel search my mythtvsetup locks to the feeds
  and gets channel listing very well. Signal strength shouldn't be an
  issue too, since Kaffeine always locks to the new channels just
  fine. Signal level/quality is also quite high.

  I think I tried almost everything, except dropping the database and
  creating it all from the very beginning. I still tend to think
  that's the last thing I shoud do...

  Does anybody have any ideas what I can do with that?

  Thanks!

  P.S. My mythbackend.log doesn't say anything about channel lock:
