Without having a copy of the EPG data it is hard to tell exactly what
the problem is, but my guess is that it is the usual problem - bad EPG
data.  Ideally, the EPG data will be like this example from New
Zealand's Choice TV channel:

        <programme channel="choice.freeviewnz.tv"
start="20190305153000 +1300" stop="20190305163000 +1300">
                <title>Birds of Paradise: The Ultimate Quest</title>
                <desc>Frank Gardner has always dreamed of seeing birds
of paradise. Frank and Benedict Allen journey across some of Earth’s
most inhospitable terrain, both haunted by brutal memories from their
                <rating system="Freeview">

This contains a unique ID for the programme in the "episode-num"
section.  When a repeat of this programme airs, it will have this same
ID again and MythTV will understand it is the same and not record it.
Without such data, MythTV has to fall back to checking the subtitle
and description data and make a decision based on that and which of
those fields you have told it to look at.  But often that data
changes, even between two playings of the same programme on the same
channel the same week.

If you actually want to record just once a week, then MythTV can do
that.  You have to use a Custom recording rule, as that is the only
place where you can do a Record Weekly option since it was moved there
many versions of MythTV ago.  You can also have SQL as complex as you
like in a Custom rule - I did one for my mother that recorded
Coronation Street episodes only if they were broadcast after 18:00
local time.  That prevented her being confused by all the repeats that
were broadcast in the afternoon.
