Before I get into the details here, in the interests of full disclosure I am also a DVD author as well as a Blu-ray author - I taught myself how to do these because I got heavily into 5.1 surround music & found there was not very much content to actually buy, so I thought 'how hard can this be' and bought Scenarist SD, Scenarist BD & Sonic/MEI DVD-Audio Creator. Turned out it was quite tricky as the Sonic tools seem to think you already know the structures and the format limitations for Video_TS imported into an Audio_TS project.
But I digress.
I keep seeing references to structure protection - but have never even seen anything to teach me how to do this, or what to look for.
How is this done - and why?
