Our Sony DAV s300 has started playing up with DVDs skipping and going back to the beginning half way through, and I have heard this is a common fault and it is likely that I will need to get a new one. -This was an all in one system with the speakers etc. Can I just get a new DVD player and plug the speakers into the back with some adapters as the current speaker cables have special sony speaker plugs on the end. (the speakers are all wired into the walls!!!) Or do I need an amplifier as well?!!! - I have been told that with the all in one systems, the amplifier is in the DVD/CD player and I could just have a scart lead going from the new DVD player into the video one phono sockets of the old player which will act as the amplifier????? Help!!!!!!!!!!!!!!
