As title implies, DP4 is running pretty darn good (Gigabyte GA965p-S3, Intel Core 2 Duo) with Q/E using NVEnabler, however my DVD drive is not recognized. Any thoughts?? thanks! ssprod

SATA or IDE? I don't know your exact board, but, if IDE, is it a JMB 36x IDE chip? If so, you will need some jmicron kexts. Look up BlackOSXs thread and he has links to kexts that will get you going.

I have the same issue.
I do not have a DVD built-in into my laptop. Mine is a USB drive. I thought it might be the drive but I have now tried three USB DVD drives and all have the same problem. It is always the same - Initialisation error -70012.

THe drive works as it reads Data DVD's fine.

I take it that it is crashing when you attempt to play back DVD movies in it? Do you have USB from an intel chipset (Southbridge) or?

I guess "crash" is too strong a word. It errors with no drive plugged in and I run the DVD Player see:

The output from Console is:
Jun 28 17:49:23 MacNBs-MacBook-Pro DVD Player[217]: kCGErrorInvalidConnection: CGSGetWindowTags: Invalid connection
Jun 28 17:49:23 MacNBs-MacBook-Pro DVD Player[217]: kCGErrorFailure: Set a breakpoint @ CGErrorBreakpoint() to catch errors as they are logged.
Jun 28 17:50:40 MacNBs-MacBook-Pro DVD Player[217]: kCGErrorInvalidConnection: CGSGetWindowTags: Invalid connection
With the drive attached, I get the same error so never get to play the movie at all.
File Manager can navigate the content of the DVD.
It is just the DVD Player that's not working.

Interestingly, I downloaded MPlayerX from the App store (a great App that can play almost anything that QuickTime cannot - even streams full HD over the WiFi). It can play the DVD fine.

The laptop is an Acer 3820T with Intel i5. Intel HM55 chipset. ATI 5470M graphics + Intel HD graphics (turned off).
I don't know the Southbridge chip.

I think quite a few number of folks are having the same issue.

Apple locked out external DVD drives from working with the DVD Player app. The two solutions are to use an internal DVD drive or use a different app to play DVDs. There is a third solution of modifying a framework to recognize the external DVD drive for DVD player, but this will lock out internal dvd drives (and hex modifying frameworks isn't a good idea).

og-phantom - thank you for finding that article.
Yes I can confirm that was the problem.
My laptop does not have an Internal DVD drive.
The DVDPlayback Framework had the DVD Player as Internal.

As test, I carried out the patching of the DVDPlayback file and set four words "Internal" to "External", repaired permissions and restarted. Started DVD Player and it now works. I plugged in my USB DVD drive and plays DVD's fine.

So now I know that the DVD Player issue is nothing to do with the ATI Drivers or any hacks.
I also take back the word "crash" - it was reporting an "error" but just not saying it explicitly.

BTW, the quality of the playback of the DVD using Apple's DVD Player does appear better than MPlayerX - especially sub-titles.

I agree with you, it's not a good idea to patch the Framework. If you do, you have to track every update just in case it is changed.

Thanks again.

Glad I could help you!!! Keep a note laying around to remind you to patch that file again if the next update changes it back (by replacing it with a new one). Yeah, I agree, nothing can play DVDs better than the Apple DVD Player ;-)
