Hi I have a samsung 40 inch Tv with Sky plus soon to become Sky HD, with a home cinema surround sound system, everything is working fine at the moment.I have my Sky plus box connected to my surround sound via a optical cable. Does anyone know if I get a Blu ray player will I be able to connect to the Tv as normal with HDMI, and to get surround sound 5.1 will I need to connect via a optical swithing box between the blu ray and surround sound. I will need the switching box as my DVD/home cinema system only has one optical output

You will need a spliter I'm afraid, I used one for years with my previous set up. You can get a simple 2:1 for about £5 & they work very well. The 3 input type have a switch on them which make them more awkward but the 2 way does not, you just have to remember to turn off sky when using it for BD player otherwise you will not get any sound as the optical signals collide. http://cgi.ebay.co.uk/2-Way-Optical-...d=p3286.c0.m14 although these say 1 input & 2 output they do work in reverse.

Has your surround sound system got an coaxial digital input? If so use this to connect the BluRay player using a digital 75ohm cable. This type of connection is considered better than optical anyway! Better still if u use a dedicated surround sound amp this should have a dedicated 6 channel input then you will get the new Dolby HD codecs which is better than plain old Dolby 5.1. Hope this helps!

Both signals are identical, there should be no difference at all.

Does it have to be a certain type of cable, as I have noticed the standard RCA ones fit the digital coax connections.
Or would this not give the right effect.

What Nigel means is that the CONTENT of the signals is the same, one is carried via an optical fibre, the other via a co-axial cable. The optical fibre ends in optical connectors, the cable ends in RCA (or also called Phono) connectors. They are not interchangeable but carry the same content.

You can use pretty much any decent co-axial cable with RCA connectors - although the "bits of string" that are supplied with most devices are a bit thin - it is a digital signal so basically works or doesn't. I've used some pretty crappy cables when desperately testing kit pre-install!
