Hi all, Hope this is quite a simple question to answer...... Is there any advantage to using a seperate optical audio cable rather than using HDMI for viseo and audio? I am thinking of buying a new AV receiver but I currently use 3 optical outs and the AV receiver I am thinking of only has 2. However, my current AV Receiver doesn't have any HDMI. If audio is fine through HDMI I won't need to use 2 out of the 3 optical leads that I currently use. Cheers in advance folks!!
