-The GUI/mkvmerge say that this is not supported.
+The GUI/mkvmerge says that this is not supported.
 
 ## The answer
 
-mkvmerge does not support reading HD DVD subtitles files which often use the file extension `.sup`. This choice was made because HD DVD was the clear loser to BluRays in the fight for the HD content storage medium.

-However, mkvmerge does support BluRay subtitles, also called PGS subtitles, which often use the file extension `.sub`. If you want to mux existing HD DVD subtitles then you have to convert them to the BluRay format first.
