Hello,
I've made some coasters out of some DVDs, and have since been using Toast's simulation mode.
It appears that the DVDs I were burning may have been too large to fit on a DVD-R. They are reported in the Finder as being 4.35 gig. This seems to be the case because smaller DVDs (4.12 gig for example) will make it through simulation mode just fine.
What is the burn limit? Why doesn't Toast warn me? (I'm using 6.0... our department at school registered the software, but I can't update to 6.0.5 without this registration info. Do the updates help fix this problem?) Should I be able to burn 4.35 gig DVDs?
Many thanks in advance for your help....

Perhaps it's a 1000kb = 1MB = 1024kb issue?

I've found 4.36 to be the limit. Maybe you have bad media. What brand is it?

Piodata.. The error I get in Toast is "incompatible format" in all caps. I get this towards the end of my burn simulation.. the last time I got it was about 1:30 from the end.

I am using 6.0.3
It does warn me if I tried to burn anything larger than 4.36GB.
Pioneer DVR-106D, Apple DVD-R media 4X, and Mac OS X 10.3.3

A simulation of a 4.1 gig burn ran through just fine. It appears as if you are right about the ceiling. Makes me wonder what the extra 300 meg or so are being used for, and why both Apple's disk burning software and Toast don't issue a warning when you try to burn too much data to a disk.
Thanks for this confirmation!

there are no extra 300 megs. 4700 MB / 1024 = 4.5898 real GB. It's the same reason your 40 GB hard drive only holds 37.13 GB. 4.35 should work, but I guess it might be a rounding problem in the Finder. How many bytes does it say they are in the Inspector window? is it more than 4,700,000?

Well, that's the reason why a 4.7 GB disk only holds 4.3-something GB...
You know, the class action lawsuit against computer and hard drive manufacturers is only going to lead to one thing... the operating system will start reporting sizes/capacity in base 10 vs base 2.

No, it's more like 4.37 real GB.
4 700 000 000 / 1024 / 1024 / 1024
