The over-the-air guide data is EIT, and as far as I know does not need
an XMLTV ID specified, as the EIT data is tagged to say which channels
it applies to, and all that is handled internally by mythbackend. You
only need to use XMLTV IDs if you are using XMLTV guide data, normally
gathered by some external mechanism and loaded from a .xmltv file.
Originally, the EIT data on FreeviewHD (DVB-T) was only Now/Next, and
you had to use the MHEG5 data to get proper EPG. But a while ago the
full EIT data was also added as a separate stream alongside the MHEG5
and Now/Next EIT data, so you can choose which you use. I have never
compared the MHEG5 data to the EIT data, so I can not say if they are
identical or not. But they come from the same source, so are likely
to be similar. The problem with using the mythbackend internal
over-the-air option to gather EIT data is that you do not get to
process it before it is used. The downloaded data has some extra
processing done using the xmltv-proc-nz script to remove nasties such
as "All New " and "New: " on the front of titles. MythTV itself
automatically removes "New " from the front of titles.
To use the MHEG5 data, either use the downloaded EPG, or run
mhegepgsnoop and load its data using mythfilldatabase. You can run
xmltv-proc-nz on the data yourself if you do not want to use the
downloaded data. I do that, and also do some more processing for
other nasties. You can also use epgsnoop to download the EIT data,
then run xmltv-proc-nz and load that with mythfilldatabase.
This is what my last run on xmlt-proc-nz found to fix:
SearchReplaceTitle: Changed from "New: Modern Life is Goodish" to
"Modern Life is Goodish"
SearchReplaceTitle: Changed from "New: Behind Bars - Rookie Year" to
"Behind Bars - Rookie Year"
SearchReplaceTitle: Changed from "New: The Blacklist Redemption" to
"The Blacklist Redemption"
SearchReplaceTitle: Changed from "New: Duck Quacks Don't Echo" to
"Duck Quacks Don't Echo"
SearchReplaceTitle: Changed from "New: Taskmaster" to "Taskmaster"
SearchReplaceTitle: Changed from "New: Bar Rescue" to "Bar Rescue"
SearchReplaceTitle: Changed from "New: Duck Dynasty" to "Duck Dynasty"
SearchReplaceTitle: Changed from "New: Swamp People" to "Swamp People"
SearchReplaceTitle: Changed from "New: Hardliners" to "Hardliners"
SearchReplaceTitle: Changed from "All New 2 Broke Girls" to "2 Broke
Girls"
SearchReplaceTitle: Changed from "All New The Middle" to "The Middle"
SearchReplaceTitle: Changed from "All New The Simpsons" to "The
Simpsons"
SearchReplaceTitle: Changed from "All New 2 Broke Girls" to "2 Broke
Girls"
SearchReplaceTitle: Changed from "All New The Middle" to "The Middle"
SearchReplaceTitle: Changed from "All New The Simpsons" to "The
Simpsons"
It is also possible to run an SQL script to do fixups of the guide
data after it is already in the MythTV database. Doing that when
using the over-the-air EIT option will not work well though, as MythTV
will be downloading new EIT data all the time, so you will not know
when there is some new data that needs correcting and be able to run
the SQL script. So using an SQL script is best done when using an
external grabber and you can run the script as soon as you have run
mythfilldatabase. I have put my current SQL script on my web server
if you want to take a look at it:
http://www.jsw.gen.nz/mythtv/epg_fixes.sql It includes fixes for my Sky channels as well as Freeview. Here is
the output of running the script yesterday:

For DVB-S, the guide data was always a full EIT feed, although now if
you download from the Sky mux that broadcasts Prime, you can also get
MHEG5 and OpenTV EPG now. I checked the OpenTV data using EPG
Collector on Windows and it is a bit different from the EIT data.
