After updating to 8.1.3.8 QT I had issues with 2 burns. Shameless season 1, disc 1 and Shameless season 1, disc 2. I was able to view season 1, disc 2 after it started with the error report “cannot correctly identify disc, cannot use network function of disc”. That displayed a few seconds then a rotating disc appeared behind that message and the disc proceeded to play just fine. On season 1, disc 1 the same message appeared but then went to black and the disc would not play. I burned it again and tried to play it, it had the same message and black out and did not play. I went back and installed 8.0.8.5 QT burned season 1, disc 1 again stuck it in the player and everything played fine. Will keep 8.0.8.5QT until issue with 8.1.5.0QT is resolved. Burned using LG super multi blue BD rewriter. Played on Sony BDP-S470.
