The DVR is set to record into /media/NGMEDIA/NugTV.

It then wants to record a program.

It wants to create a .grab directory there for capturing the stream but
because it has no permission in one or all of

/media
/media/NGMEDIA
/media/NGMEDIA/NugTV

it reports it can’t capture – which is true.

Where you need check is if:

  1. plex has read-execute on /media
  2. plex has read-write-execute on /media/NGMEDIA
  3. keep going all the way into where .grab is created under NugTV where it also needs read-write-execute.

Here’s the How-To about getting DVR permissions correct on Linux.
