how about DVD10/DVD14?
Correct me if i’m wrong here but i think :
DVD10 is just a flip disc.
DVD14 is a dual layer on one side and single layer on another.
DVD18 is a dual layer on double side disc. Basically 4 recording layer.
Any reader/writer can read DVD-9 should be able to read any of these. but of course you need to manually flip it.
Hope this help.
ic, so 166s will not have problem reading those disc?
Nope, it shouldn’t
