It is insane MKV is no longer supported. And I hear people around the web claiming "it is a niche format". It is NOT niche and is WIDELY used in all sorts of places on the Internet. In fact, I'd say it's probably the most common container for web-downloaded media. Insane. Adding a tremendous amount of added work on the user's end for no clear reason and removing it unannounced. Terrible decision. If there were any application half as good I would already be gone.
For Adobe to just remove it and say "Sorry, you can't have this anymore. We never REALLY supported it" is asinine. Just put it back in. Whatever reason you really removed it probably isn't very good. Use your billions of dollars and fix it.
