Transcoder Issue with Plex DVR

Hello. Im running my Plex server via OpenMediaVault through Docker CE. I was able to get all my movies, photos, and music working on Plex. I was also able to get my HDHomeRun Connect and HDHomeRun Dual connected to Plex for Live TV. The only thing that doesnt work is the DVR service. Every time i try to record a tv show it immediately says “There was a Transcoder Error.” I checked the logs and this is what i could see.

My tuners do work, as i just canceled my SiliconDust DVR service after a year to switch to Plex. I just recorded a show last week with the same tuners.

Also i am on Plex version 1.14

Please disregard this. the solution of me was removing the noexec permission on the folder where the trans-coding was trying to happen. so far looks as if the show is recording.
