I'm looking for some advice on connections. I currently have a Denon DHT500SD 5.1 home cinema DVD system which has always served me well. However, I've recently ordered a Sony KDL40Z4500 LCD TV and a BDPS550 blu ray player. At present my budget does not stretch to a new AV receiver and speakers (I'd rather wait and save up for a good system). For the time being I hope to use the DHT500SD as a makeshift amp. I understand that I can connect the BDPS550 to the DHT500SS via a digital optical cable (or coaxial cable - what is best?), but there is only one optical cable input on the DHT500SD (also component and digital coaxial). What's the best way of connecting SKY+HD? Is it via the TV through the HDMI connection and then out DHT500SD using component cable or, alternatively, directly from the SK+HD box to the DHT500SD using either component or digital coaxial? Just trying to establish a connection if this is possible. Any advice to a novice would be most welcome!!!
