Question for Mac Pro owners w/Pioneer DVR-112D superdrive..what firmware revision?

[yeroen]

For those whose Mac Pro came pre-installed with the Pioneer DVR-112D superdrive, what firmware revision is it running?

The reason I'm asking is that I have an aftermarket 112D, bought from OWC, that I purchased for it's rip/burn speed advantage over the pokey, possibly riplock crippled, Sony DW-150A that came with my Mac Pro. This advantage was indeed gained, but at the expense of living with some quirkiness with the drive, namely the "two-ejects required" problem discussed here:
https://forums.macrumors.com/threads/287227/

This quirkiness has gotten worse since the latest Mac Pro EFI firmware update on 09/27/07. Now if I'm watching a movie from a DVD in the 112D tray, any extended pause (and by extended I only mean more than a minute or so) causes an unrecoverable error in DVD Player and I'm forced to restart the DVD Player and restart the movie.

My suspicion is that this all has something to do with some (overzealous?) power management feature in Mac OS X that's not playing nice with the existing 112D firmware (I'd be interested in hearing any other plausible theories).

Currently, my 112D firmware is at revision 1.06. There a number of updated firmware revisions for the 112D circulating on the internet, PC centric, of course and mostly related to disabling region-locking etc.

I'd like to match my 112D firmware to whatever Mac Pro owners with a 'bona-fide' 112D enjoy, if it's publicly available somewhere.

Thanks.

Patchburn

Have you installed Patchburn? Check out this link:

Thanks for the response.

Yeah, I ran patchburn when I installed the drive. But keep in mind Patchburn only generates a 'device profile' in /Library/DiscRecording/DeviceProfiles which is referenced by Disk Utility, iTunes etc. for writing to the device (in particular, write speed parameters, type of media supported, etc).

This problem appears to be at a much lower level.

As far as I can tell (everywhere but Pioneer), the latest DVR-112D firmware revision is 1.22. I was wondering if this was what the 112D's delivered with Mac Pros had; or if as one may suspect from Apple, some under-the-table non-publicly available Apple-specific firmware.

Thanks Fezzy.

That AC08 (AC=Apple Computer?) was what I was looking for. I'll look for it. Let's hope it's not too under-the-table.

Mine is also AC08, if you care.
