I actually find the quality of DVDs to be very good with the right equipment. I’ve seen DVDs projected in movie theaters and they look good. There are bad transfers and I’d certainly take a BluRay over a DVD if there’s an option, but overall DVDs are still a solid format that I still use regularly. I’ve never had the urge to actively seek out an update to something I already have on DVD, though I might grab an upgrade if I see a sale or the mood takes me.
