Problems with Hybrid SACD's ?

My Sony 9000es plays Hybrid SACD's fine up to a point. It then glitches, always at the same point on the same disk, and go's silent. These are "square label" hybrid disks. Is it a problem with the player, disk format or the specific disk? My guess is that it is the disk or it would not play the disk at all. the Sony plays single format SACD's just fine. This is the second Hybrid disk I purchased and both disks did this. Do I just avoid hybrid's
