At first, it was all VHS. Then I switched to all DVD -- transferring copies of VHS to DVD.
Over the years trades, grey-market torrent downloads, burned DVDs and my bought DVDs have all been transferred to files on my computer. I then watch them on my TV using Plex media server.
I know this is very high tech but it organizes all the movies by year, theme and so on.
How does everyone else watch their noir? Is it mostly DVD?
