Hello, I received my zidoo z9x yesterday.
I did some tests and no DV file passed. Even the dvtest demo files from here. I have a black screen.
For others they open only in HDR10.
The firmware is in beta, but for dolby video it is more alpha. In addition there are bugs with some televisions (LG, Panasonic)
And it comes from the zidoo because my internal player reads these dv files well.
The Shield is better, especially they are very reactive, before zidoo released products quite well finished, now they release products not usable and have served as beta tester.
