These Discs are J peg Photos that I have recorded on my Computer. Sharp sent me an update Memory stick which I updated the Disc Player. I wondered if I should be recording the J pegs on DVD +RW or DVD +R Discs or DVD -RW or DVD -R
Go to the front of your blu ray player's manual and it will tell you what disc to use and the ones that you can not use.
It's a formatting difference between the cpu and dvd player that won't allow it to work plus you must use the correct disc.
