1080p Blu-Ray copies would certainly be doable, but I don’t know of anyone (including the members of the 4K77 forums) who is capable of authoring and burning a 4K Blu-Ray that is playable in a standalone player. I for one put my 4K copies on a flash drive to plug directly into my TV and watch them through my TV’s built in media player software. Most UHD BR players are capable of this as well.
1080p Blu-ray discs are fine, I just do not currently have the means or knowledge to do it myself. Any assistance would be greatly appreciated!
