do people just say dvd to mean any physical disc? i get it if so, just have never personally heard it

blu rays still come out with some good extras, commentaries, making ofs, interviews and stuff but i guess it’s more niche releases. often with books, posters, art cards as well. in the uk i have some nice ones from:

arrow 88 films 101 films eureka second sight bfi shameless films

haven’t got much from overseas but had some region free luck from north american vendors vinegar syndrome, severin, raven banner, and umbrella entertainment from australia (also region b)

would welcome recommendations for similar labels if you have them
