If I understood you correctly, yung Samsung HTIB mo has a built in DVD player. then nasira na siya.

Yung Philips mo naman is a plain DVD player. is that correct?

If that is the case, di talaga gagana yung speakers mo dun sa philips since wala itong amplifier section unlike the Samsung HTIB mo.

You need a receiver to connect the DVD to the speakers. But you should be careful in matching the receiver with your speakers. If you are not sure. Better get a new HTIB.
