@ChuckPa Thank you for the heads up. I will upgrade to 515 and test next weekend to be prepared.
I am having a similar problem with the exact same GPU. In my case the VAAPI errors are stalling hardware accelerated playback. It seems like pms is attempting to use VAAPI before eventually failing on one device and finally using the nvidia P400 after a 10-20 second delay.
My currently installed drivers are nvidia 525
PMS version is 1.30.2.6563
I followed the steps @seanwo1 described and set HardwareDevicePath to “/dev/dri/renderD129”, but when looking at my logs I saw this:
Jan 17, 2023 06:43:33.848 [0x7fb752996b38] DEBUG - [GPU] Got device: , unknown@builtin, default true, best true, ID /dev/dri/renderD128, DevID [15ad:0405:15ad:0405], flags 0x0
Jan 17, 2023 06:43:33.848 [0x7fb752996b38] DEBUG - [GPU] Got device: GP107GL [Quadro P400], nvidia@unknown, default false, best true, ID /dev/dri/renderD129, DevID [10de:1cb3:10de:11be], flags 0xe
It appears the P400 is not the default GPU rendering device. How do you assign the default rendering device for plex?
Logs for reference:

For you… due to no QSV in a 2013 xeon, there is no renderD128, The Nvidia will be on renderD128 because of how the kernel initializes (CPU then PCI devices in sequence)
D128 didn’t seem to help. The transcode eventually shows up in nvidia-smi and plays but only after a long delay. Sometimes the delay is long enough for report users to get the network error
Attached are logs created after the latest PMS update and D128 changes.
