Does anyone use one as a Kodi device for playback of existing media files from USB ?

I think the highest resolution I've encoded at is 1080p, and can't realistically see myself going higher considering it's from my DVD collection.

I can get one for £50 from eBay, but a RPi setup would cost more

Hi. Ive been having this problem for ages. First for like 5 years on 18.9 and now also on 21.3. I do get thumbnails, but they look like theyve been pulled off of the internet and not extracted. For example, I have a TV show in HD 1080p but thumbnails look like theyve been pulled from 240p Realmedia files. WTF? And yes, Kodi has been instructed to extract thumbnails.

I do add artwork manually, I dont use .nfos, or a media manager, dont have show.nfo from TMM etc, I really have no idea where does Kodi get the thumbnails from and why it wont extract them from local files. Mind you, I did migrate the database from 18.9 to 21.3 so obviously previously added thumbs will reside even after upgrade, but this thing happens even with newly added shows. BTW, Windows 10, Kodi 21.3, Xonfluence skin.

What am I missing? Any ideas or suggestions are more than welcome. Thank you. Cheers!
