Hello all,

I burnt some home movies to a bd r with cdburnerxp which said all the
files were burnt to disc correctly. But when I test the disc in my and
my fathers blu ray players a message come up saying "unknown disc".

I tested both players with another bd r from the same tub that I burnt
last year. Both player recognise this disc.
So I then split the home movies as to fit on a dvd r.
Same error on both players.
Both players play cdr, dvdr and bdr that I burnt last year and still
both play blu ray movies that I bought.

Why is this happening?
