actually movie, ads, fed warnings etc are dead easy to skip when ripping/ backing up. I'ts been ages since I've bought a DVD ( that is such an obsolete format
) but back when I was buying educational ones I would routinely make a backup via DVDFAB that had all the ads n stuff removed.
Netflix / AMazon Prime don't put non skippable crap at the start of their films
Many dvd players have firmware hacks that make everything skippable, even the stuff that the studios want to force you to watch every time. Usually it's the same hack the removes the region blocks so you can actually watch any dvd you buy. I recall googling and adding those to bought dvd players back in the day. Ah, the nostalgic wonders of DVD DRM
Back on topic: anyhow I just happened to pick movies rather than say music CDs as my peeve analogy. Would you really want opening epigraphs, dedication etc tracks on each of your music albums. Perhaps something aposite by the billy goats gruff:
or would you just say , no problem I am happy to start playback at track 3 not track 1 every time ?
