How can I get my new receiver to decode the AC-3 s
I have a laserdisc player with an RF AC-3 digital output. However my Sony DA4ES will not output sound when I make that connection and force it to use it. Is the receiver incapable of decoding the AC-3 signal? I just assumed, being a close relative of Dolby Digital, that it would "get it". The receiver properly decodes all surround formats output from my DVD player. Any thoughts would be appreciated.
