Toast 19 on Mac uploaded Data size of Classic vs Updated

[Steve Mtn]

As a first time user of Toast 19 on Mac , not finding the Toast user guide to have many needed details.

Creating a Blu-ray Disc with Toast 19 pro on iMac with Catalina OS.  Uploading 20.03 GB of 8 related slideshows created with Final Cut and compressed with Compressor.  When uploaded to the classic menu view it shows 18.34 GB  on the disc (-1.69 GB less than the original) and the updated view shows 30.89 GB on the disc (+10.86 GB more that the original).

The classic view burned on a 25 GB Blu-ray Disc, but prefer the menu and chapter options better with the updated view.  Thought the GB readout on the updated view might be an error, but it would not burn on a 25 GB disc.

How can there be less GB on the classic but more GB on the updated view?

How do I resolve this?

Thanks.

I did not realize there was a "Classic Mode". How do I set that -- I think I have gone through all the menus and preferences, but I must have missed something!

Thanks!

I am having the same problem, a problem detecting file size in 'Updated' mode, but in 'Classic' mode it works just fine. This is for a regular mpg file. The mac file system has it at about 4gb, which would fit on my disc. But the 'Updated' mode in Toast 19 reads it as 5.7gb, so it complains my file 'exceeds capacity' of the disk, and won't load it. But in 'Classic' mode, it sees the true file size just fine, and even writes the disk successfully. So for me, with Roxio's clearly hosed customer service model, I'm just going back to Nero. A bit retro, yes, but so much better. But wait, that's not on Mac. True, but I use Parallels, so I can do it on my virtual Windows machine, on my Mac. Problems solved. Sad though. I really wanted a less complicated, all-Mac solution.

Update:

So the Nero/Parallels scenario doesn't work all that well either. The DVD writer is read-only in Parallels, which sucks. So my new workflow is to start up Parallels, customize the DVD content and output to a video_ts folder using Nero (because I still prefer the Nero authoring environment), then I go back to Big Sur on the Mac and use Toast 19 to burn the video_ts folder. Ugh. Too much back and forth. But it works.

New Update:

So now I just got my DVD drive to burn the video directly from Nero running under Parallels, without any help from Toast 19 at all. Now I'm feeling like I spent a pile of money with Roxio and got nothing for it. Sigh. Live and learn.
