Can’t say for a DVD, but smart TV’s are likely to go the way of 3D TV’s, they are here today and will be gone tomorrow. In my case, a 60-inch Samsung Smart TV, I’ve abandoned the Smart TV part and replace it with a Roku Premier. The advantages are more apps, integrated search across all the apps(amazon, netflix, HBO) and much more.
My Samsung had HBO GO, but I didn’t; it doesn’t have HBO Now, but I do. Apps would disappear overnight without warning, others, like Skype, would give 3-months warning and disappear forever. The Smart TV had no update control, always seemed to want to update when I wanted to watch it and more.
Overall, Amazon Fire Stick, Google Chromecast, Roku etc. have outperformed Smart TV’s in speed, features, and most especially apps. Thats not going to change, TV manufacturers don’t have deep enough pockets, long enough vision, and enough experience to catch-up
