When you create a DVD DL video disc, the rules are slightly different depending on +R vs -R, but generally you want your data divided evenly between the 2 layers. The burning app needs to know exactly where you want to split all that data - you tell it by designating a Cell for the layer break. Now a cell is like a bookmark - a specific place or time in your title video file - and Chapters only can occur wherever you’ve got a cell... in DVDA you create cells only by creating chapters. Long story short, when DVDA asks for a chapter, or any burning app asks for a cell number, they’re asking you to exactly define where you want your content split.

There should be earlier threads with more details if you’re interested, plus many people feel the best way to burn a DL DVD is with ImgBurn, or the older method using PGCEdit + ImgBurn... you can find guides & links to guides on their respective sites.
