Unable to Correctly Detect Space Requirements for DL DVD

After copying DL DVD to ISO image, I initated a burn of ISO image to DL DVD. ImgBurn gave message: "Dual layer DVD not necessary, Do you wish to burn anyway"? I wondered if maybe the space didn't actually require a DL DVD. Therefore, I inserted a single layer DVD into drive. Then imgBurn told me that "There is not enough space on this DVD".

 

I replaced the original DL DVD blank and initiated the burn again, this time ignoring the message that a dual layer DVD was not necessary. The DVD burned and worked perfectly.

 

Just a small message problem that I wanted to report.

The checks are done using predefined values (sizes of discs).

 

If your drive reports a lower capacity than the predefined values, that could be why you were having the problem.

 

Also note that sometimes it'll tell you the image can fit on a DVD-R disc. That doesn't mean a DVD+R disc will work too - it might not as they come up slightly smaller.
