>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.

Fixing DVBChannel is in my long term plan...
