I download the Rytec EPG file http://www.xmltvepg....ytecSE_Basic.xz. A lot of the entries contain repeated texts in the XML node "desc lang". They are then displayed twice in the channel info on my Dreambox DM500HD. Here is an example of a node with repeated texts:
<programme channel="SVT2.se" stop="20211124204100 +0000" start="20211124203400 +0000">
<title lang="sv">Kulturnyheterna</title>
<sub-title lang="sv">[Nyheter] (2021). [Sverige]</sub-title>
<desc lang="sv">Kultur- och nyhetsprogram. Kultur- och nyhetsprogram.</desc>
</programme>
