@Emmanuel_perez Hello agian.
Re:
It shouldn’t be required but it’s definitely the way to go I would say as the last CentOS based released is 3.9.2-57 and we didn’t update the elrpo kernel-ml it used for a very long time. Where as our ‘Built on openSUSE’ offerings have an upstream (openSUSE/SuSE) maintained kernel. So in that sense alone you are more likely to get better hardware support/fixes/improvements. Especially for newer hardware. Plus any fixes/enhancements we release of course.
See the following forum thread for the progress on what is currently Release Candidate 6 (4.0.5) released as of yesterday (3rd Jan 21):
I’m not familiar with using quicksync myself but as long as you have post 3.9.2-39 it should at least be an option within the Rockon install.
For the nvidia support and it’s associated hardware acceleration elements you are again advised to go the Rockstor 4 route, again for the newer kernel and current OS underneath, i.e. CentOS 7 for Rockstor 3, openSUSE Leap 15.2 for Rockstor 4.
Hopefully others more knowledgable / experienced in this area can chip in as I’ve not tried the Plex hardware acceleration yet myself, although I have a machine lined up ready to try it. As you have gathered the feature itself, within the Rock-ons config area, was added by our forum Admin and major contributor across the board @Flox.
Note that a fresh re-install will be required to move to the ‘Built on openSUSE’ but your existing pool/share/snapshots can be imported in the same way as in the CentOS variant. And if you first save/backup you config (and download it), much of you settings can also be imported. See the following doc section of config save and restore:

Hope that helps.
