I switched several months ago with good results. Advantages I see
are <br>
20 days of listings<br>
Season and episode included with each program<br>
Channel icons automatically downloaded included if you update your
channel list from the downloaded schedule.<br>
<br>
Disadvantage is it uses a lot of memory, so I created a script to
run three days at a time instead of all at once. With version 29
there is a "noallatonce" feature to address this.<br>
<br>
For switching over, I first set up the channels in xmltv
(tv_grab_zz_sdjson_sqlite), then deleted all my channels from mythtv
and re-added them from the xmltv download. <br>
<br>
Be careful if you decide not to delete all your channels, use
--only-update-guide, otherwise you could get them all added again
and land up with channels duplicated.<br>
<br>
If you delete all channels and re-add them, it may allocate
different chanids to channels. If this happens MythTV could show the
wrong "recorded from" channel for recordings. By default when
loading it names chanid as SXXX where S is the source and XXX is the
channel number. Sometimes this scheme goes wrong and different ids
are assigned. If the existing ids match that scheme then reloading
will use the same scheme.<br>
