Is the use flag actually doing anything? Reproducible: Always Steps to Reproduce: 1. mpv dvd:// 2. 3. Actual Results: stream: No protocol handler found to open URL dvd://menu stream: The protocol is either unsupported, or was disabled at compile-time. Expected Results: Play the DVD. DVD is fine, and is accessible to the system (dd if=/dev/sr0 works fine). Judging by the error message, the ebuild is not including dvd support properly.
Looking at the ebuild for media-video/mpv-0.9.1, it says this: dvd? ( >=media-libs/libdvdread-4.1.3 dvdnav? ( >=media-libs/libdvdnav-4.2.0 ) ) "man mpv" has this to say about dvdread: Play a DVD using the old libdvdread code. This is what MPlayer and older mpv versions use for dvd://. Use is discouraged. It's provided only for compati- bility and for transition. So, does "mpv dvdread://" work? Does "mpv dvd://" and "mpv dvd://menu" work if you enable USE=dvdnav? The ebuild has IUSE="+dvd dvdnav". Since upstream apparently prefers dvdnav, maybe that should default to on as well?

Yes, "mpv dvdread://" woks here fine. And rebuild with USE=dvd dvdnav "mpv dvd://" and "mpv dvd://menu" works fine here. Thank you :)
Indeed we need to either enable dvdnav by default or merge this flag with 'dvd'.
Created attachment 403826 [details, diff] changes required for >=mpv-0.8.3 ebuilds Since commit https://github.com/mpv-player/mpv/commit/8ce73ebbe0167a7a6fd3555a9fe24b4f8f3202e2 dvd:// defaults to dvdnav, so having separate 'dvdnav' USE flag is pointless.
