I occasionally get burned BR's and sometimes dual layer (Verbatim) BR"s sent to me from a friend with various video on them. It's hit or miss as far as them working. I have 2 BR players in the house, a Sony and a Samsung. Many times the discs won't play in either of them. They are both roughly 5 years old and barely get used.
I don't understand why all burned DVDs seem to play fine without exception, yet when you pop in a BR it's an adventure as to whether the #$^@ thing is going to play or not. Don't know if buying a new Panasonic player will solve anything but I am considering it.
