Itunes movies - Blank screen - High Sierra

[L0rdLogan]

Seems like a small issue in comparison to others.

Itunes 12.7
GTX 970 - using latest web drivers
Intel core I7 5820x
Gigabyte X99 UD4-Wifi

Everything is setup the same as it was in Sierra, SMBios is the same, and apart from Clover giving me an error about APFS on boot and the loader being messed up, everything works as it did in sierra. Apart from Itunes movies.

Se images for what I mean regarding the Clover boot - Clover v2.4 R4220.

That sounds like Shiki to me - had the same behaviour with iTunes DRM media in Sierra before installing it and a support kext for my 960. One or both may need updates.

Huh, Alright. I never needed that Kext in Sierra. I'll give it a look.

Thank you

EDIT 1: Tested that, using a tutorial on getting it fixed and it didn't work

I have the same text over MOBO logo thing. The screwy clover screen I fixed with a new theme.

iTunes movies are fine.

Woah! Non-itunes movies are fine. iTunes purchased movies don't work. Hmmm

I know nothing about shiki...

In my ACPI>patched folder I have a file named SSDT-HDMI-HD530.aml this rings a bell in the past. I suspect this has something to do with it. I think I need to make a new SSDT now my configuration has changed, I just can't remember where I found the patch...

Looking at the verbose output, I think I have found the problem, amongst all the text is this:

.

.
ApplHDAEngineOutput:erformformatchange (<ptr>. <ptr>, 0)
IG: ME PCI ACPI device not found - PAVP services will be disabled - add IMEI to EFI / ACPI list
IG: DRMStatus - iTunes/Apple Store Content Access Problem. Content playback may be disabled on this computer. You can continue to use the machine, but you should contact an Apple support representative. ErrorCode: 8877652.
[IGPU] Graphics Scheduler Preemption Disabled!

Please forgive the blurry image, I dropped my phone.....

The boot-up problems are a side issue to this and seem quite sporadic.

See post# 165 in 'iTunes 12.7 Constantly Crashing' those steps worked for me with iTunes blank screen, movies not playing etc etc with a GTX card. May help with your problem.
