Item that is scheduled for recording does not show up nor does it record it.

I was able to successfully record a show with my HDHomerun, but when I specify a certain time to record it doesn’t show up in the recording schedule and it doesn’t record anything.

I want the ability to record a show at a certain time only.

Do you have minutes before start set on the recording? If so you will need to remove the padding. Plex is not finding a show that starts at for example: 6:59 pm if you it set to start 1 minute before the show airs.

Will Plex Devs fix this or do they not see it as a problem.

There is an issue filed for this problem.
