I've been obsessively curating my DVD collection since 2002. I never had much interest in HD. When I bought a new TV in 2015, I got a 720p LG model, going for the lowest resolution I could find since most of what I was watching was old TV shows shot on crappy video formats like the original versions of Doctor Who and MST3K. But then my DVD player crapped out on me last year and I finally got a replacement. Since Sony BluRay players are cheap these days, I got one of those. I borrowed a few BluRays from a friend to see if I could see the difference compared with my DVD copies. I can, particularly in dark night scenes and darkly lit interior scenes. (For reference, my test BluRays for this were The Avengers: Age of Ultron, Ghostbusters (1984), and Sherlock Holmes (2009).) Now, I'm torn as to how far down the upgrade rabbit hole I'm willing to risk going. I'm a completionist by nature but I know that it's impossible for me to upgrade my entire collection since a lot of it is stuff that never came out on BluRay, either because it was shot or edited on a much lower format or because they just decided not to. (Some shows are new enough that they could have easily gotten a BluRay release but didn't for whatever reason, like Burn Notice and Community.) And one of the things I love is organizing all of my DVDs on the shelf in alphabetical order and looking at them. Frustratingly, BluRay cases are so much smaller than DVD cases, so I'd have to either put up with some massive visual irregularities or else separate them into their own section. I realize that this is a massive First World Problem, but how have you dealt with this situation? Any tips on the aesthetics of it? Are there any particular criteria you use for which titles are worth upgrading? For older FX-heavy movies, is there a point where the higher resolution just starts to emphasize the flaws?
