It is the same, only DVDWS is more intuitive, and takes more CPU, and takes longer. Honestly, there's no need for chapters in a 22-minute episode (unless it's a multi-story episode). And chapters every 5 minutes in a 40-minute or longer episode is just fine.
How many people actually use chapters? Not many.
This is one of those things I rarely put effort into. Like disc artwork, it something few people appreciate. Work is better utilized on quality DVD menus and DVD cases (and quality video/audio!).
