DvdSp's layout

I "create" the Dvd folder (with Video TS and empty Audio TS) in Dvd Sp and then I burn with toast... (Data Dvd Rom Udf)

Dvd Sp always leaves a specific "layout" of it's own in Video Ts. (with a DvdSp icon)

I always trash it before burning with Toast, I am right to do that ?

You should make the dvdsp Project Region ALL and output a .img out of DVDSP and use that. In Toast or Disk Utility etc.

If you want to use Toast, newer versions will remove the .LAY & .layout files if you use the from VIDEO_TS folder option as well as adding the AUDIO_TS folder. BUT you still should flag the build as Region ALL with MyDVDEDit or another editor. Then burn.

If you must use the Data DVD ROM UDF option then you need to manually remove the .LAY & .layout files, flag the build as Region ALL and then burn the Folders etc.
