I guess so. Interestingly, if I seek, it detects PCM for a short time
before reverting to AC3, so it looks like something crappy is sent along
the optical link cable that doesn't look like AC3 at all. Or when I
press Q or hit the enter key to finish playback.

Whoa, do I sense some animosity against this library? I understand it is
a big mess, and I still have some discs that don’t play along well with
it, but it currently is the only way of playing most of the copy
protected discs (mostly older (i.e. 2006-2012) Sony and recent
Paramount), where dvd:// simply gets stuck on corrupted sectors and such
stuff. And with some Disney and Paramount discs, where I use dvdnav to
find the correct title (because there will be 99 titles, and most of
them with the same length, but all with different chapter numbering…).

Yes, no more silence on chapter breaks. Thanks!
