DVD players do not drive speakers. The unit that you have been using has a receiver built in. A new unit to replace it may come with its own speakers. If you have a separate DVD player, you can replace with a receiver, but the sub may not be useful with most receivers. The rest of the speakers may.

It is not a DVD player. It is a DVD/Receiver aka home theater system less speakers.
