Hi, I have a Philips DVD player with only a coaxial output and no 5.1 decoders. I have just purchased what I thought was a 5.1 AV with decoder from bid-up tv only to find that it does not have a decoder !!!!! Is it possible to buy a coaxial to 5.1 pre AV converter, if it is not obvious from the details above it also needs to be very cheap !!!!!!!!! The only other solution that I can think of is to buy a very cheap (£45 DVD player with decoder). Are these normally any good?
