<< Is this common? >>

A hybrid disc has a semi-transparent SACD layer halfway through the disc and a reflective CD layer at the top surface. To read the CD layer, the laser has to travel through the semi-transparent layer twice. This obviously will degrade the signal to some degree.

I don't know how common it is for CD-only players to have problems like this, but it does happen to some degree.

Another problem is that some DVD players and DVD computer drives will see the SACD layer first and think that a DVD disc has been inserted. But it can't read the "DSD" information, so it just gives an error message and spits the disc back out.
