> The data is generally sent spread out across multiplexes ("set of

> for a while to figure out what data is being sent for those
> channels, then tune another multiplex and listen to it to figure out
> what's on those channels, and continue for all the multiplexes.
> Then, by the time it finishes, the data may well have changed for
> some of the channels (or have been updated with further listings
> data or ...), so it starts the process again.
> If you don't like your tuners being in use for it, you'll need to
> either find another source for listings data (like some XMLTV
> source) or you can choose to disable "Active EIT" in your capture
> card settings in mythtv-setup:
> Use DVB card for active EIT scan
> If enabled, activate active scanning for program data (EIT). When
> this option is enabled the DVB card is constantly in-use.
> However, if you do, you will only get "passive" EIT scanning,
> meaning you will only get EIT data when you're recording (recordings
> and Live TV), and only for the multiplex on which you're recording
> (meaning you could lose all data for a given multiplex if you don't
> record from it or at least tune it in Live TV often enough and for
> long enough.
> If you want high-availability listings data, and want to use EIT,
> you really do want active EIT. You could disable it on only one or
> a couple of capture cards, but choose carefully how much to disable.
>> Is mythfilldatabase used also for EIT?
> No. It's only for filling the database with listings from XMLTV or
> Schedules Direct.
Thank you very much for your detailed explanation.
