They are infrared LEDs, and a simple way to test is to point it at a digital camera, maybe a web cam (don't use one myself), and you should see it flash on the screen, when you press buttons. Check the remote batteries, make sure they are good, and installed correctly. I've got a remote that isn't marked, and batteries can go in either way... On the DVD player, try to locate the receiver, make sure its not dirty or obstructed. LEDs seldom fail...
WOW really embarrassed now. Just discovered that you cannot control a Phillips (not Samsung) DVD player with Samsung remote. Wifey has just passed the correct remote to me. Blush.
