Currently, all programmes are being displayed as “new”. This is because the <previously-shown /> tag is doesn’t appear anywhere in my XML.

Please read the FAQ.
We give you the data which we receive from the stations.
We do not create the data.

If the channels provides the data about the show being a rerun, then we also put that tag into the xml file.

There are enough channels and enough shows with that tag.
Many channels do not really care about their data.

Many of them send their data even in outdated excel sheets.
