I’ve bought a lot of physical media over the last couple of years and it can be great, but there’s a lot of pitfalls
The quality of, particularly, DVDs is all over the place and the transition from NTSC to digital is handled in so many different ways that each require special handling.
PAL and European releases can be terrible in all kinds of ways including speeding up the content and optionally pitch correcting the audio.
A lot of content you’d want isn’t available or is only available at exorbitant prices.
UHD discs have tons of read errors that make ripping perfectly difficult and the quality (and this price) of the drive makes a big difference in how well you can do this.
Drives don’t last if you’re ripping lots of stuff.
Just some things off the top of my head, nowhere near a complete list.
It’s still worth it, though, and new releases are easier if that’s what you’re looking for.
