Dual Disc Problems?

I have two players, a SONY SCD-XA9000ES and a Music Hall Maverick. The Sony plays DualDisc about half the time. The Maverick doesn't play them at all. I bought 1 DualDisc (Springsteen) and won't be buying any more.
Playing a DualDisc shouldn't, as far as I know, have any effect on any discs you might try to play afterward, unless the disc actually caused problems closing the disc drawer. Then all bets are off.

Isn't "Dual Disc" and "Problem" redundant? Who asked for these things? The more the music industry "progresses", the more I wonder about it all - failed audiophile formats, suing customers, bringing out "CDs" that don't adhere to the redbook standard. You have the malicious Sony virus. I have never tried so hard to be a good customer and been given so many reasons to give up on those efforts. I just love the way music execs have every reason under the sun that their 20+ year old business model doesn't work anymore for reasons other than that they haven't been able to figure out how to adapt.

I refuse to support this product!

What are Duel Disks?

My understanding of dual discs are discs that contain multimedia software in addition to the music, so that you can interact with them via a computer.

My first RA Opus 21 had a lot of trouble with these discs, and an Ayre CX-7e hicupped occassionaly also.

But, my new Opus player has no trouble with them.
