In short, you will have to consider purchasing a replacement remote control. If the original is not available, a universal remote may do the job. Universals are obtainable practically anywhere and can be preset to recognise the device of virtually any brand; in your case, the DVD player. Most functions will work with such remotes, but not all can be guaranteed. I hope this helps a bit - and the (universal) remote won't cost an arm and a leg to buy either.
