Welcome to the forums kedolby.
There were never very many people here who used DVDReMake Pro, and most of those haven’t been around for a while.
I do quite a bit of work with dvds, but I use completely different tools, and tend to work with elementary streams, rather than try to work with entire dvd-video structure when merging and making a new dvd menu. But stick around, someone may have some help for you.
You may also want to ask your question over at videohelp.com. I’m sure there are still a few DVDRemake users there.
