I must update the Tutorial, but then again I have little time to do so, as you know I dont come here often anymore.
Just use the Internal DVD Author and it will do the job for you, it works great and is free. Just select DVDAuthor in the Image tab, set Subtiles to be on and select DVD Subs, that way you can turn them on or off when your playing it on the TV. You can use Ifoedit to have them turned on by default if you prefer.
The Tutorial with Maestro is the DVD to DVDR tutorial
