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.

Dolby Digital is AC-3 (and vise versa). I agree with Ncarv that the problem is not the receiver, but probably the Laserdisc player RF signal is not the same as a DVD player signal and therefore not compatible.

Are you sure your Laserdisc player will read Dolby Digital?

I will check with a videophile friend who knows a lot about laserdiscs. He has owned all the variations in laserdisc technology going back to the original Pioneer analog players. I have his old first generation digital laser player, and I've never tried to run it other than in Pro-logic.

I am back... My friend sais you will need the RF adapter. He has a Kenwood 990D player that has a coaxial output like a DVD player (also the RF). So he does not need the adapter. Pioneer made a few later players this way also. If you don't want to spend the $100 for the RF adapter you could look on eBay for another machine.

Also Pioneer currently makes a DVD/LD combination player. The regular DVD coax output works for laserdiscs also.
