If you have a 5.1 sound system which has a fibre optic input, then this is a must have! The sound is so rich and beats any dvd player hands down. It can actually do 5.1 surround sound and DTS instead of the standard pro-logic.
That combined with the s-video makes it a great multimedia experience. The s-video inhances the picture quality so dvd's and games become sharper looking.
I have to say that buying this cable is worth its weight in gold!
