i got the same problem, actually i update to 1.2.0 version, but doesn’t fix the dvd issues, maybe a problem with cios incompactibility? because it was working good the dvd playback after version 1.1.9, y really don’t use it frecuently, but if some day i want to see data from dvd drive, or dvd movie, cuz i have my vids streaming by wifi from my pc, but knowing that i have this problems, it feels like i have no all the funtions working good.
Also that drive test doesn’t work either, maybe if the programmers could made a patch for this problem, because i still having problems after update it to version 1.2.0, and they said, the problem was fixed with that realese.
I hope u response me.
