I'm sure this has been covered in part or in full before, but I didn't feel like digging through old posts today. Two questions:1. Has a convenient way of determining whether or not a film is in Dolby Digital-EX arrived? 2. What happens if your EX is engaged on your processor (we've got a CP500 with the add on EX unit), but the film is not encoded for EX? Does the rear channel just drop off all together? ------------------

It is impossible to tell by looking at a film whether it has an EX track unless of course it is written somewhere on the leaders. And as far as I have seen no film has had 'EX' written anywhere on the leaders to date. Which leaves you to researching (web, print info, etc) to find out whether a particular title has EX encoding.Leaving the decoder in the EX mode will usually just matrix out a 'pseudo-EX' channel from non-EX tracks (in fact, Smart recommends leaving their decoder in EX mode for all films.) -Aaron

Check the Dolby web site http://www.dolby.com to check out the latest EX encoded film lists. "Auto-EX" should now be happening on newer films. The CP-650 and new SA-10 adapters will detect the "EX bit" to auto switch. Older SA-10s must be upgraded for auto-EX. Depending on the film, leaving the EX decoder active will have either a pleasing effect or it can collapse the surround track into the rear channel (if the surrounds were not really mixed for stereo).
