Laszlo, I may not state the problem very clearly. I saw two problems: 1. ParitionDxe shouldn't create BLK handle for the entire media again. Our QA complains several new but unexpected BLK devices are seen. This bug is easy to fix and needs to be fixed ASAP. So I created a BZ (https://bugzilla.tianocore.org/show_bug.cgi?id=707).
2. PartitionDxe should handle multiple LVDs in a UDF CDROM. No one complains this. I am fine to accept the limitation. So I even didn't create a BZ. Anyone who wants this support can submit a BZ. I guess following the same pattern of existing code to support it should be easy.

Paulo stated he had never seen such media. Can you share your reproducer media perhaps (even privately, if it can be done legally), or else provide instructions to create, or obtain, such media?
