The problem may be that only the cDvbDevice creates a cSIProcessor,
and the first cSIProcessor created sets up the "schedules" list (see eit.c).
So if there is no cDvbDevice, this may not work.

In version 1.3 the whole section stuff (and with it the EPG handling)
will be changed, and there I'll make it so that it doesn't take any cDvbDevice
at all.

For the moment you could try to do

  cSIProcessor sip = new cSIProcessor("dummy");

somewhere in the analogtv plugin to create a dummy cSIProcessor.
I haven't tested this, though, and don't know if it will work
at all. It's just an idea...
