Noob here, trying to burn Blu-ray with multiAVCHD

[beantrouser]

When I click on Destination Path, and I select the D drive (labelled "d: []") which I believe to be my burner, multiAVCHD gives me a pop-up box that reads "I/O error 1.". I click OK, and the destination path stays on the C drive.

What do I have to do to get multiAVCHD to burn a disc??

I'm using:
BD-R 6x/25GB disc
Asus BW-16D1X-U Blu-ray burner
multiAVCHD v4.1 (build 771)
I've got ImgBurn 2.5.8.0 installed

My computer:
2014 iMac
4GHz Intel Core i7
32GB 1600 MHz DDR3
AMD Radeon R9 M295X 4096 MB
Bootcamp running Windows 10

Don't use multiavchd to get imgburn to burn your folder,use imgburn directly and burn the folder.

Destination path is the location you want your created files/folders stored before burning. This must be a physical drive, not an optical drive.

The first time you check the Use Imageburn... box under Settings, you will need to select the location of the Imageburn executable. Also, ensure Imageburn is set up to recognize your desired optical drive.
