Tvheadend

You haven't said which Tvheadend version you are using but AFAIK this function is already available in the current master.

Go to Configuration -> Channel/EPG -> EPG Grabber Modules -> FreeView and set the Scraper Configuration to "uk", then tick the "Scrape Title" box.

Version 4.3-1916~g1884300f0

And DVB-S not DVB-T.

I already have the Freesat EPG and Freesat EIT Grabber configured to scrape title and set to UK.

I'm going to erase the EPG and set the Freesat EIT Grabber to have a lower priority than the Freesat EPG Grabber, to see if that corrects the issue (And would mean that the Freesat EIT Grabber isn't scraping correctly?)

My apologies, I misunderstood how the 'scrape' function works.

The scraper doesn't alter the title or summary of a broadcast, it adds extra data fields to the EPG. If an event title begins with "New:" or similar then the is_new flag is set, and this can be used when setting up autorecs (see the 'Broadcast Type' field).

If you are setting up autorecs based on the event title, according to the documentation the title field is a case-insensitive regular expression, so an autorec for "Grand Designs" should also record "New: Grand Designs" if the 'Broadcast Type' field is set to 'any'.

Suppose the programme title is a single, common word, so your expression needs one or two anchors, like ^banshee$. This would not match a programme title like

New: Banshee

To this end, I've used optional groups to good effect:

^(new: )*Banshee$

In other instances, I use non-capturing groups, like recording only the original Grand Designs series, and not the two offshoots:

((?!.*(Australia|New Zealand))Grand Designs)
