I’m new to AnyStream. Been using anydvd for years. Looks like file created is mp4 with embedded subtitles. I play ripped bd discs as movie only iso file on Dune Solo 4K. Works great. I can not get subtitles to play on Dune in mp4 or when demuxing mp4 with tsmuxer and them remuxing. Read many posts and so far behind didn’t find methods. What workflow do others recommend if playing back as mkv or iso container? Also are chapter marks part of the stream?
