First Blu-Ray and "There was a problem playing this item"

The facts:

  • error happens on all devices
    -.mkv file
    -name: The_Castle_of_Cagliostro_t00
    -File plays fine in VLC player
    -all other files from the disc play fine
  • 1.5 TB free on drive
  • only the feature has the error

Ideas? Thanks,

Never mind - created a temp folder in my 1.5 TB free drive for transcoding. Seems to have fixed it.
