Can't play recorded dvd

I’ve been trying to play my dvd-rw media recorded on my LG DVD Recorder onto my SONY DRU-810A dvd drive. But i can’t seem to be able to watch my recorded show even after finalizing it. Why ?

What type of DVD-RW media is it specifically? (e.g. Memorex, Sony, Verbatim…etc) or better yet, what media type is the DVD-RW? (e.g. MCC, TY, RICOH…etc)

What format was it recorded on?
