+*:The original author disabled adaptive reading
+  specifically in 0.79.6 (see changelog below), as it
+  doesn't handle RS03 correctly yet. In this patchlevel
+  we enable it again for media without (detected) ECC data,
+  and for media protected with RS01 or RS02. If we detect RS03,
+  we tell the user the behaviour is unpredictable/undefined,
+  and recommend using linear reading instead.
