I've been curious about the layer break issue myself. I'm on OS X and have burned many football (american) games on to DL media using Toast. I build the VIDEO_TS folder from DVD Studio Pro and then let Toast auto set the layer break point. This has always worked fine for me. There seems to be no option in Toast for setting the layer break point yourself like in DVDDecrypter on Windows. So it sounds like the layer break point is embedded in Citizen's authored VIDEO_TS, is this right? And Nero or Toast or whatever reads that? If so, then I can go ahead and burn it on my mac at home keeping the correct break point instead of having to take a hard drive to work and burning it there?
