From the stack trace it looks like this is due to the lack of input
handling code in DVBChannel. This is an old bug, but TVRec used to
have special case code to work around the DVBChannel bug which I
removed not knowing what it was. I just committed a fix which
should prevent this DVBChannel bug from causing a segfault without
needing special case code for DVBChannel in TVRec.
OK -- unfortunately now I get a different SIGSEGV. I'll have a dig
around in a bit, but you probably have more idea of what's going on than
I do. The frontend, for the few seconds it is running, displays "no
lock, signal 0%" for all channels (in browse mode) and no output if
that's of interest. Attempting to change channel then causes the problem.
With the 0.18 release I get a picture and channel changing works ok. If
you want me to try anything else, then I'm happy to do so.
Thanks,
Mark
