For now you need to create an MKV file with makemkv. And it should contain only one video track with the base layer (BL) and enhancement layer (EL) interleaved. This is known as STDL (single track, dual layer).
What you have now in BDMV format is an M2TS file with two video tracks, which is known as DTDL (dual track, dual layer). CoreELEC cannot play this as DV yet, but @Portisch is working on that at the moment.
