Yauiclient hang when trying to update recurring recording

[artmetz]

I was going to replace this recurring recording, but wanted to look at the details first by clicking on the Update button when the hang occurs.
I see some exceptions shortly after this point in the nrecord.log
2026-09-19 09:03:52.033 [DEBUG][71] LoadListingByAdvancedRules(channel='all channels',advancedRules=title like 'Woodsmith Shop')

I had to remap the PBS channels some time ago, thus the 0 for the channel. I just hadn't bothered to update them since they kept recording.

Does it work with the default skin? This breaks the server-side doesn't appear to be yauiclient related.

Code:

Same issue with the Default skin.

Probably something in the database then, that we doen't like, we'd need a link to your npvr.db3

Got it. How did you enter a -1 in the post padding for a manual recording, that is the problem.

To fix it go into the web scheduler and change the post padding to 0.

Ok.
Could it be the type of recording was changed due to the channels being remapped? I likely set it up as a normal recurring recording and with PBS I typically set the post padding to a negative number.

The issue is you probably don't understand that you can't use negative padding in UI clients, which is why you must have used the web to enter them in the first place. There is a bit of a hack on updates to set pre-padding to zero when it is negative and that will be added for post-padding for the next release but the best solution is to just use the browser.
