Try "andere tijden$" where the final dollar should mean "match the strings that finish with what precedes the dollar".

I will try that but the problem is why a valid (according to testsites) Regexp is not saved and disappears.

Seems very similar to the following issue:

[[https://tvheadend.org/boards/5/topics/19220]]

Probably identical. But there is no response to that issue.

I also can confirm this issue and with some experimenting the following problems I found:
- It seems that the ? in "andere tijden(?! sport)" is the problem maker of not showing the regexp in the gui AND NOT in the configuration file;
- After entering "andere tijden(\?! sport)" it appears in both GUI AND configuration file but is not working. The configuration file shows "andere tijden(\\?! sport)";
- After manually changing the configuration to "andere tijden(?! sport)" it not appears in the GUI and also not building a queue of recordings.

It seems that there is a problem with the data transport from server <-> GUI and the implementation of processing the regular expression.

Note that we use glibc posix extended regex which does not support some other regex extensions. Your tester does not support that. Try http://www.regexplanet.com/advanced/golang/index.html

I'll look why the string is not displayed in GUI.

The regex is not saved, because it's not valid posix regex. TVH behaves correctly.

Thanks for the info.

Could you direct me to a place where I can get information on the syntax? or (better) find some examples which I then can modify?

'man 7 regex' . The http://www.rexv.org/ shows the whole posix syntax in help left column, too.
