TV Recordings stuck in .grab

Just got Plex to act as a DVR. It works pretty great, except when it doesn’t.

Some recordings are coming out fine. But I notice that some get stuck in some kinda of post-processing loop, and then disappear. The files are in the .grab directory for a while, and show with a red disk (instead of a play button) in the “Recording Schedule” view

It’s been a few hours and they seem stuck there:

Eventually they aren’t in the .grab directory either, but still show with a red disc:

For instance, where is the recording for NOVA?

myth@mythbackend:/var/lib/mythtv/plextv$ find . -type f | grep -i nova
myth@mythbackend:/var/lib/mythtv/plextv$

Is it because it was “cancelled”? I don’t know what “Cancelling operation for … with status complete.” means:

myth@mythbackend:/var/lib/mythtv/plextv$
myth@mythbackend:/var/lib/mythtv/plextv$ grep -ri nova /var/lib/plexmediaserver/Library/Application\ Support/Plex\ Media\ Server/Logs/  | grep -v mythrecordings.log

I have the same issue, did you find a fix for this?

The issue is now resolved (on mine). I believe it was due to incorrect Plex permissions in the Ubuntu file system. The NAS was longer overdue for a rebuild, so I backed up, reinstalled Ubuntu and PMS following this guide. The only other thing I did was to set the Plex DVR device settings to “CONVERT VIDEO WHILE RECORDING > Transcode”.

It’s still an issue here using Plex Version 1.12.0.4829
I’m recording OTA to a local drive. The program has been watched and ‘deleted’ yet the episode is still listed in the hidden .grab folder with a log file in the deleted show folder updating constantly (constant disc access) and after a few says is no over 50GB. This has happened a few times before. My only solution is to quit the Plex server. Despite that the log file continues to be written to, then delete the episode folder file in the .grab folder and relaunch Plex server. It’s an annoying ongoing issue.
