Toast 11 Titanium Blu-Ray burn problem is solved.
Well it's been a long and winding road... sorry for the Beatles lyric, it betrays my age. I finally found the solution to my Blu-Ray burning problem. I've been communicating with Roxio's Customer Support's "Antonio" in regards to my problems previously listed here, everything Antonio offered in the way of potential solutions did not work. Tsantee here helped as best he could (I assume Tsantee is a "he") but to no avail. On a lark and totally out of the blue (no pun intended) I decided to disconnect one of my optical drives from my Mac Pro platform. I have two optical drives in the Mac Pro, the top one is the Blu-Ray burner jumpered as "Master" and the bottom optical drive is the OEM DVD burner that came with the Mac Pro and jumpered as "Slave".
At first I tried reconfiguring both optical drives in various configurations of "master", "slave", and "cable select"... all to no avail, I continued to have Blu-Ray burn problems. So I seemed to remember reading many years ago, when I first purchased/installed the Blu-Ray burner, reading somewhere on the 'net that having two optical drives in a Mac Pro COULD cause problems, but at the time I was only burning DVDs, not Blu-Ray discs, so there were no conflicts using DVD Studio Pro authoring DVDs with either optical burner.
Like I was saying, on a lark I decided to disconnect the OEM DVD burner completely from the system, kept the MCE 12x Blu-Ray burner as "Master" and proceeded to burn a Blu-Ray DATA disc ... NOT an authored Blu-Ray movie disc ... I just wanted to burn DATA to Blu-Ray ... and voila! Success.
The "Success" came only if I create a DISC IMAGE file using Toast 11 and THEN "copy" that disc image file to a Blu-Ray disc using Toast 11 Titanium and it's been functioning flawlessly... no more error codes, no more verification errors.
Here's the "fun" part... I did this after work hours on my own time literally minutes before I was to leave on a week's vacation, you have no idea how relieved I am. This solution works whether I'm burning data to BD-R 25GB or BD-DL 50GB media.
I informed Corel Tech Support's "Antonio" about this solution, he said he's put it in his notes for future customer issues.
I'm not saying this is the problem everyone else is having burning Blu-Ray discs using Toast 11, but at least in my case it IS the solution to my particular problem.
One more thing... Corel/Toast claims (and so does their Tech Support folks) that in order to burn anything to Blu-Ray media using Toast 10 Titanium or Toast 11 Titanium, that you HAVE to purchase their Blu-Ray HD Plugin (their terminology, not mine) for $19.99. But if you drill down in their tech specs, Corel clearly states that Toast 10 & 11 Titanium can burn data to Blu-Ray natively, with no mention of needing to purchase their Blu-Ray plugin to do so.
BUT, and it's a big BUT... if you want to author Blu-Ray movie discs, then you DO have to purchase their Blu-Ray Plugin to get their nifty (not) HD quality Blu-Ray menu screens.
I made this Blu-Ray plugin "issue" clear to "Antonio" that there is no need to purchase their $19.99 Blu-Ray plugin to burn DATA to Blu-Ray media and he said I was still wrong but when I succeeded at burning DATA to Blu-Ray media WITHOUT the Blu-Ray plugin, this cleared up his misunderstanding and I'm sure to Corel's Sales Department's chagrin.
So if there's a way to get the word out as this being one potential solution, please do so. This had been dogging me off and on for two years now and that's only because I'm starting to run out of disc space on my Mac Pro's HDD's of which I have over 14TB of external HDD capacity for video editing. I'm currently offloading tons of .MOV files in 1920x1080 multi-GB size and even burning individual files to BD-DL 50GB media that exceed a BD-R's 25GB limit ... I have many files that exceed 38GB that are "master" video files of finished video products I want to archive them in their native DVCPRO HD 1080i resolution.
The ultimate acid test was for me to re-copy these burned files back to a hard drive... they have all been successfully copied back to any of my HDD's, so this solution works for me.
Good luck all.
