At least one other option is to use a program like tv_grab_dvb to grab
the EIT stream to an intermediate XMLTV file, and then use this file
to populate both sources with the same data using mythfilldatabase.
The downsides to this method over that provided by the patch on the
above ticket include:
i) the timeliness of EIT data is lost unless you also regularly grab
the now/next data from the EIT;
II) you tie up a DVB card whilst grabbing the data
Having a working cross-source solution in the code itself would
benefit not only the many users with DVB-S/DVB-T combo backends where
there may be differences across EPGs, but also provide another route
to provide EIT data to non-digital sources where no native EPG is
