I can't relate that line number to the current code listing (it doesn't seem right).

I can't replicate this issue. You could try clearing out the xmltv cache.

Alternatively these type of errors can indicate a failure to retrieve the target web page

try rerunning the config to check for a transient error
check your dns is resolving for www.tvguide.co.uk and my.tvguide.co.uk and you can retrieve the website:
```
wget  https://www.tvguide.co.uk/channellisting.asp?ch=74&cTime=
```

Agreed it's currently working. I think the source server updated. (I wanted --list-channels; I already have a configured grabber. I'm afraid --configure was broken for weeks before I noticed.) There was a previous error https://github.com/XMLTV/xmltv/issues/64 which lasted long enough for a patch. The server sometimes moves channels around so there's no guarantee that a given channel is available for --configure to download to scrape the channels list. The grabber could try multiple channels or sample randomly (channel ids are just numbers for this grabber).

It has only been necessary to change the channel id used for fetching the channels list once in seven years.

If the channel id for BBC1 (the channel used to fetch the channels list) ever changes then it's trivial to change the id to another one.

Please don't hijack other threads.

Check that file exists, is readable, and that it contains valid data, and if so then open a new issue.
