What was the trick. I didnt see it on the post.

Sorry, I think you mis-read. I didn’t say I burned a blu-ray with dvd studio pro. I stated that “I just burned a dvd in dvd studio pro.”
Just to let you guys know that the macpro did interact with the lg drive.

I contacted lg directly twice and one said it will work on a macpro with toast and the other didn’t recommend it.

I’m pulling the drive. Thanks for everyone’s input

I appreciate everyone’s support. I suppose that’s the reason apple
hasn’t signed off on it despite others saying it works. I know it works, I just burned a dvd in dvd studio pro. But I believe you are correct in “the delicate balance has been upset” Just in the case this comes up somewhere down the road, here is how system profiler sees it:

HL-DT-ST BD-RE GGW-H20L:

Firmware Revision: YL04
Interconnect: ATAPI
Burn Support: Yes (Generic Drive Support)
Profile Path: None
Cache: 2048 KB
Reads DVD: Yes
CD-Write: -R, -RW
DVD-Write: -R, -R DL, -RAM, -RW, +R, +R DL, +RW
BD-Write: -R, -RE
Write Strategies: CD-TAO, CD-SAO, CD-Raw, DVD-DAO
Media: Insert media and refresh to show available burn speeds

and OWC Other World Computing sells this drive as compatible as long as you have toast. https://eshop.macsales.com/item/LG/GGWH20L/

Thanks again for everyones input

Thanks Bob.
1a Per a recommendation on the blu-ray, I plugged into the sata port under the fan directly into the lg. I have had some success and some extreme lock-ups.
1b Tried disconnecting the lg but the sony still did not work
2 Sorry, I did re-install the kona drivers. Not sure if it matters but using the horita csg-50 rather than bsg-50 but it was terminated. I have switched to freerun in the control panel.
3 It was while listening throught the kona3 output. I tried the computer output and the sound was clean.
5 Compressor has been working again even prior to this post but I cant seem to find anything in aja control panel under any tab about quartz extreme. I know you said it may be another name.

As I mentioned, I believe for whatever reason, when I uninstalled Toast the problem in playback may have stopped but I really want to use toast. I am also curious about what your response will be about the blu-ray burner. Thanks again for your help.
