NO. SD still supports the DataDirect format, with channel selection
through the web-site, and downloading data using the mythfilldatabase
However the tv_grab_zz_sdjson and tv_grab_zz_sdjson-sqlite programs
provide data from a different base, with more/better data, and reduced
server load at the SD end, and reduced computer load/bandwidth at the
user's end. Program data is separated fropm scheduling and downloaded
once. Schedules for channels are not re-downloaded if unchanged.

I just did some checking. It appears that the entry in mythtv-setup ->
General -> (scroll to the bottom ) Program Download Options (or
somesuch) -> and setting mythfilldatabase OR /usr/local/bin/my-grabber
actually does not control the download.
*THAT* is set in mythtv-setup -> 4. Video Sources ->
Your-named-source-here -> Select grabber option from the LONG list. In

My OTA.xmltv file covers the US channels I get through one of my antenna:
# NOTE the '!' negating the lineup
and continuing list of channel/xmltvid pairs

'He who dares, wins'. If you are not getting what you think you should
be getting, then give it a try.

Nothing to the xmltv world. It is a completely parallel world which is
only accessed by using the mythfilldatabase program from your mythtv
box. (With General -> Program Download... -> mythfilldatabase AND forex
Video Source -> OTA -> mythfilldatabase.

Of course you can. If you are using the JSON xmltv setup, that is done
through the JSON configuration process, OR, as previously set out, using
mythtv-setup -> Channel Editor.

I guess I will have to go look at the wiki and see if the setup process
can be clarified. Last time I looked it seemed reasonable to me, but
then I *knew* that it was completely different from using the one and
only! original mythfilldatabase off the web-site. (I've been using the
JSON xmltv route since 2015!)
