Hi jryhnglw and welcome
It's an error related to the verification process when using VSO as the burn engine (VSO is Fab's default burn engine).
The "verify" function is useless with VSO. It's not reliable and only causes problems.
Open Common Settings > Write > untick
Verify disc after finished burning
or better yet
Switch to Img (<---link)
for your burn engine. It's much more reliable and much more configurable.
It is fully supported by LUK! (dvd decrypter) and you can access it within Fab Platinum or Gold.
Please make the following change in Img:
tools > settings > build > don't prompt image details
This will make SL burning a seamless process. The Img window will still pop up, but won't require any action from you.
For DL burns, you'll still have to select a layer break location just prior to burning...unless Img has already created an .MDS file which contains the LB info
