Can anyone PM me or post the best way to convert the MKV to a BD WITH a Menu and retaining all the audio tracks? I have demuxed the whole thing, and tried rebuilding it in DVD Architect but it didn't like the DTS files, nor the H264 video. I tried renaming the h264 to mp4 etc...and nothing seemed to work. Please no comments about just using the MKV and using a streaming device (which i already have...) and telling me how physical media is dead, blah blah blah. Or telling me to just wait...
As I understand it, there are no freeware Bluray authoring packages (or even affordable commercial packages) that can handle the number of audio tracks in the mkv.
I believe MultiAVCHD can create a Bluray with menus from an mkv directly, but only with a limited number of soundtracks.
Check back through the thread as Harmy intended to try a 30 day trial of software that may support all the soundtracks.
From what I recall about DVD Architect, you just use it to create the menu and then manually edit the structure to shoehorn in the Bluray files.
I think you may have to ditch some of the soundtracks to get this to work right now, or worst case, create two versions of the movie with half the soundtracks on each: using MultiAVCHD.
Physical media is not dead, but I think the population is starting to move to streaming services instead: granted more work needs to be done to make it more stable, however why buy physical media when you will only watch it occasionally due to there being so much material to choose from.
So much material is available in mkv format that it is more cost effective to get a media player or Bluray player that can handle the format on attached USB drive than converting to optical media each time.
