Buffering when playing 1080p on AppleTV with QNAP TS-653D

Hello Chuck, yes, I switched off the subtitles and all was well.

Still the Gemini Lake hw transcoding performed worse than the one for the Apollo Lake CPU. Futher investigation leads to multiple mentions for Intel, Synology and QNAP platforms similarly effected, for instanc When will HW transcoding be fixed?

The workaround you mentioned in this Post (QNAP HW transcoding stuttering) works in so far as the movie plays correctly including transcoding:

  1. PMS 1.19.5 for QNAP now provides direct access to Preferences.xml in the “PlexData” share in File Station.
    -or-
  2. Install / use PMSLibShare
  3. Using a Linux (not Windows) text editor (QNAP text editor is recommended), Add VaapiDriver="i965" before the closing /> at the end of Preferences.xml . Put a space before and after this setting.
