Thank you for the logs.

  1. I am seeing ‘BURN’ in your playbacks.
    – Check that your players are set to “automatic” and not forcing “burn”.

  1. Also in the log, because the libraries are installed, the ARC 750 is being utilized

This addresses two of your concerns:

  1. Subtitle burn-in — Known and will be released as soon as we finish the 6.8 kernel fire

  2. Arc GPU support – Is as I have stated elsewhere in this forum; Arc will work when the drivers are installed via the VAAPI interface just as AMD does.

To address your stuttering issues, I recommend using a remux tool (MKVToolNix) to remove unwanted subs from the file without altering the video or audio streams. This will alleviate the burden on your CPU until such time as we resolve the current forest fire and release hardware subtitle burning.

THEN – If there are no other :fire: , we’ll be able to do the major transcoder upgrade we’ve been trying to do for a few months now.
