So Iím running Toast 17, trying to burn a Blu-ray. I decided to make a Toast ISO file out of the disc first (because it takes so long to encode) and then burn said file afterwards (so my BR drive doesnít have to sit there turned on all day). Toast says the data for the disc comes out to 40.58 GB under Output Summary. The resulting ISO file came out to 52.45 GB, and so when I go to burn it is says my BD DL doesnít have enough space to fit it. How can I fix this issue, or at least get Toast to give me an honest and accurate file size without losing an entire day encoding an ISO I then canít use?

Thanks.
