    Can't import MPEG2 MKVs any more after OSX update?

    GWR71 Level 1

      My work-supplied MacBook Pro recently had to have a system drive rebuild, so I ended up with High Sierra on it rather than El Capitan.

       

      Now, I can no longer import MPEG2 MKVs to Premiere Pro (CC 2017). I used to be able to do it, but now I get a "file format not supported" message.

       

      Is this because I'm now on High Sierra? Is there any way to work with MPEG2 MKVs natively, or do I have to transcode first? Even Media Encoder refuses to import the files, so I'm having to transcode using iFFMPEG.
