It's a question that might sound simple, as the basic answer is, yes most Blu-ray players can play DVD discs. But when you dive a little deeper things start to get more complex. There isn't just one type of DVD disc and the way these are played back, in the same format or upscaled, also varies.
Follow these steps to resolve playback issues. On your device, press and hold the Power button for ten seconds or more to turn it off. Unplug the AC power cord from the wall outlet, and then plug it back in. Turn on the device. Press the Eject button and remove the disc. Set BD-ROM 24P Output to Off. On the supplied remote, press the HOME button.
Few computers have built-in optical drives, so external ones are the alternative for reading, writing, and playing back disc media. These Blu-ray drives are not the same as Blu-ray players—while they can play Blu-ray movies on your computer, they’re also designed to write and read other kinds of data stored on Blu-ray discs.

Blu-ray collection: 529. DVD collection: 138. One of my blu players, my cheap sony bdp-1100, has lasted 2 years so far and that's playing it every single day. It has serious mileage on it so, it really just depends on the optical drive. Sometimes you get a great one and sometimes you get a lemon!
