Hi, I am trying to to burn a .mkv formatted video file and its accompanying .srt formatted subtitle file on to a Blu-Ray disc, but I am having no success using Nero 12 Blu-Ray. The software recognizes the .mkv file but will not recognize the .srt subtitle file. When I click on show "all files" I can see the .srt file and can highlight it, but when I click on OK I receive an error message. Is there something I am doing wrong with Nero? Or, do I need a different software application to copy both files on to a Blu-Ray. I would appreciate if someone could recommend the best software for accomplish the task at hand. Thank you in advance for your help.
