Mark Levinson and dual layer SACD

Hi, I recently bought a couple of dual layer SACD's and found that my 390S could not see the cd layer. Strangely it plays DSOM, also a dual layer, OK. has anyone come across compatabilty problems with SACD's playing on CDP? The SACD's in question were Bob Dylan and Sting.

Regards Jim
I have no problem playing a SACD/CD disk on my 390S - the CD on the 390S sounds as good or better than the SACD on the Sony 9000 DVD player.
