For me a valid reason to connect a BD-Drive would be optimization of write/read compatibility. Standard players are not always very good at reading home burned discs in all possible formats. Other reason is always having the same functions/features/remote and overall user experience. As I hardly burn discs anymore, probably won't do it myself, but nice to know that it can be done. My SATA optical drive tests worked really well. I might do so if commercial protected discs would be supporter too, this inclusive UHD BD playback.
