Not sure if best to post this here or in Plasma...... anyway. Please can someone offer me advice on the best way to connect the following kit. Sony DAV-SR4W and NTL box to Sony KDE-P42XSI. For picture the Dav and the NTL box only have output of RGB Scart. The P42XSI has RGB scart and component. For audio the P42XSI has Digital Optical, can I utilise this ? Thanks for any advice/help.
