Well, really this is more for archival and/or viewing directly from a disc in a hardware player. That said, the menus do mostly work on a PC with Kodi, though with some extreme lag (like 30 seconds) between when you click on an option and the current menu stops / the next menu comes up fully or the selected video starts. Not that it helps you any with your network media player of choice.
So on a Sony blu Ray player there should be no lag, correct?
Probably. I don’t think he would have bothered releasing this set at all if it didn’t work acceptably on decent hardware players.
