It's kind of an unintended side-effect - it wasn't intended to work with D1 levels because D1 doesn't support POGs. However it has been brought to my attention that some versions of D1 work with .DTX files. I need to investigate what happens in D2X-XL, and between these will figure out how to deal with D1 in a way that makes sense.
