So, what happens when you get the message: "A valid video device could not be found for playback [-70017]" on your Mac


So, what happens when you get the message:

"A valid video device could not be found for playback [-70017]" on your Mac?

Well, first let me say ... I looked at forum after forum and most seem to have tried to capitalize on this phrase so you'll have to view ads … but, they never give the reason you got the message , nor do they give the fix for it. Not even the Apple forums give the correct answer - I believe that the solution has been removed on purpose.

Here's why ...

The reason you got the message, that still allows your DVDRW/CDRW combo drive to read and to burn discs, is because you installed the operating system from another computer using a cloning program or tried to use the hard drive from another Mac.

That's it! 

Don't tell me there's any other reason. Don't put in the comments that you tried a fresh installation (that's authorized and legal) and it still gave you the message.

Plain and simple, every version of OSX after Tiger 10.4.6 (or thereabouts) -  must register components as it is installing the operating system.

So, therefore, your drive will work - it just won't read DVD video discs.

The "invalid copy of the operating system" won't allow you access to the video hardware acceleration for security purposes.
