File too large to fit onto DL disc

[daviddoc]

Is there a way to get around the problem when IMGBurn calculates that the file to be burned won't fit onto a DL disc? I am trying to burn an 8.5 GB MKV file containing a BluRay movie but that won't fit into the approximately 8.1 GB space on the DL disc. I tried to play around with DVD Shrink to see if I could decrease the total file size but that program won't even recognize Matroska MKV files. Am I stuck having to only burn files no larger than 8.1 GB or buy a Blu Ray burner and Blu Ray blank discs? Thanks.

How large exactly is that file? In bytes if you would, please

Better still, what are the values ImgBurn comes up with on the 'Information' tab once you've told it to calculate the image size? (post a screenshot or something)
