yes, you can use OSex to rip out DVD Folders, or an image.
I usually do the following:
Use OsEx to rip out a Toast compatible DVD Image. Instead of selecting element streams, select DVD Image, or Folders. I do Image because sometimes OSex crashes on me when doing Folders.
After it's done, I usually mount the .img file with Toast. Then point DTOX to the VIDEO_TS folder on the mounted image...
That's it... and hope this helps.
