ConvertxtoDVD7 - error generate DVD image style silver negat

[rfolly]

Dear Srs.
After rendering video files to generate a DVD (arqiovos vob), several videos are generating a negative (silver) style image where only the outlines of moving objects appear in the background.
the files I use to generate the DVD are in H265 standard
What's happening in software?
I have tried to return the default settings and nothing solved.
See attached picture of the DVD videos with images that try to enter and exit all the time and in this interval, the image is "silver negative".
Best regards
Raphael

It would help if you could state what version are you using. And better still post the log file.
