No offense taken
I just can't see what I can do different as there are no settings I can change to make Plex not change my files to 576i max, which is just yet another issue I have with Plex, been using it for quite a few years but it seems (to me at least) to get more and more buggy.

Thanks, as it turns out its Plex not liking the mkv's that makemkv creates and plays them as 576i at best, so it seems I can't use this rather nice program for what I need sadly....

Hey, some has been DVD iso's yeah but others have been blu-ray iso's in 1080p, and yes I know about Plexiglas, but that sadly seems to be the only platform for me to stream to my different devices.

Heya, sorry if this is a dumb question but I've recently come across Makemkv and found it very easy to use to turn my iso and omg files into mkv files for Plex to read, however what I didn't notice for some time was that all my files ends up as 480p even 1080p original files, which makes it useless ...
