Similar problems here, no video, no sound etc. (16.1.0 on Windows 7 64 bit) and the mpv version cannot even be installed/downloaded ("error connecting to host"), good service, why it is not possible to download a mpv version directly ?
Youtube is not important for me but I wonder about this SMTube, too, is it outdated now ? Reaslly nothing happens,"loading 10% or so" and at 100% after some minutes and if one writes something into the search field the same again and not a single link or video or anything is shown at the end of the process, seems complete nonsense to me, do newer versions of SMPlayer still depend on SMTube or not ?
Would be good if the host with the mpv files would be active again some time in the future at least (just for testing some features etc.)
