I recently installed MythTV 0.21 on my Ubuntu Server 8.04. It has a
TechnoTrend Budget C-1500 (DVB-C) card with a Multicrypt CAM which has
worked perfectly with MythTV 0.20 on Fedora Core 5 so far, but now I'm
Very often when tuning to a new channel when watching live TV I will get
the letters LMS. which will after a few seconds turn into LMSc and then
nothing more will happen. When it gets into this state it usually starts
doing it for any channel I try to tune to, but when I try often enough
it sometimes clears up and will tune to a channel it previously
couldn't. If I restart the backend the situation usually clears up for a
while (I can tune to a channel which wouldn't work before the restart).
This is annoying enough, but even more frustrating is that it also
happens when recording scheduled programs! The symptom is that the
recording appears to start fine, but when I try to start the recorded
program in the frontend I get the message "the recorded file cannot be
found" (I'm paraphrasing), and sure enough if I look in my recordings
directory there is no corresponding mpg file and nothing has been
recorded. (I don't actually know whether this is the same problem, but
it does seem likely.) It does this about half the time, which is
extremely frustrating. I've already missed many programs I would very
much liked to have seen...
This didn't happen at all with version 0.20, recording scheduled
programs was rock solid in that version, so it must have something to do
with changes in version 0.21 (or possibly the OS since I also went from
Fedora Core 5 to Ubuntu Server 8.04). I'm hoping the good people on this
list can help me find out what's going on. I have a couple of specific
* What does the C in LMSC stand for (for that matter, what do the other
* Why didn't version 0.20 have the C?
* Can I turn off whatever it is the C stands for? 0.20 didn't have it,
and it also didn't have this problem, so apparently it's something I
don't need and can cause problems.
* What can I do to generate more debugging or logging information in
order to investigate this problem further?
