Black Screen iTunes

Whenever i try to watch a movie with iTunes, i get a black screen with this message in the console:
iTunes[381]: GVA error: AGPMGetManagedPortForAccelerator returned 0x4 for VP4
This is the same build as listed in my profile.
I never tried watching movies on this computer before so this could have been a problem in Yosemite too.

Hi Luke328900,

this is a common question that has been asked many times whenever someone wants to play DRM iTunes movie content on a Hackintosh

please see this thread

So is there a solution to this? Maybe a different fake cpuid?

it will not work with Intel Ivybridge, Haswell nor Broadwell under Tonymacx86 method nor CloverEFI method

there is a bootloader called Ozmosis but it is not supported by this site (probably because it involves you modding your BIOS with all the required files and then flashing the BIOS). This is a somewhat risky endeavour and if you do not have a dual BIOS then it's not worth the risk AT ALL + the leaning curve is steep.

I've read quite a bit about Ozmosis recently and someone commented that DRM protected iTunes contents plays on a Ozmosis Hackintosh but i don't know how much truth there is to that as no one has published a successful build on this forum that mentions this?
