I am also not sure, but after testing one afternoon and evening, where every
single recording fails
because of Popen, I did upgrade and suddenly recording works. So no idea what
exactly was causing
the problem, but yes I use mplayer and it complains at startup about not
finding lirc files, what is
no problem as I do not want it to use lirc ;-)
Maybe I can prevent that from happening with -nolirc, but then now it is
working...

Did you already solve the issue? I am using autoshutdown and
autoshutdown.timer. After the allowed
idle time, the gui of freevo (main.py) shuts down, but the system never reaches
the point, where the
shutdown command for the system is issued. Thus the system keeps running and
when I check which
processes are still there then I see the recordserver is also still alive.
Actually I have no idea, if the recordserver was ever stopped cleanly here, or
if it was killed,
when the system went down. In the log messages of the recordserver there is
nothing special at the
time of the shutdown of the gui, it seems not to notice that at all.
This is from main.log:

There is a Traceback concerning kaa. Is it save to update kaa to the current
svn version? Maybe this
will already fix the problem...
