I tried to author a DVD from a mkv file of a wedding - the person who filmed it is now deceased so I can't get much information. I managed to use DVDFlick that worked and my friend is happy with the results. However when I used AVStoDVD my preferred application I kept getting this message

Run-Time Error '35600': Index Out of Bounds

I got the same error when I used ConvertXtoDVD and DVDFab

Basically it gets to about 99.9% and then bombs out without producing the VIDEO_TS folder and files.

Just curious as to what caused this as it has happened a few times before.
