Fire TV Multipart movie audio issue

[dpi027]

Server Version#: 1.32.6.7468
Player Version#: Fire TV Last version (I don’t have access to it atm)

I have a two parts movie with multiple audio tracks. At the beginning of the movie I select one track (French, which is like the 7th track). At the start of the second part, the movie start with the first audio track (English) and I’m unable to switch to another track.
I have tested the same movie on the web player and it works fine, so it seems to be only a fire tv player issue.

I had some difficulty merging these as well. You need to perform the merge action first, before applying any other processing – immediately after ripping. I had to use a trick on one of those movies, before I was able to merge them: use MKVtoolnix to cut 2 seconds from the beginning and end of the files. I assume that the length of the video and audio streams was not perfectly the same, so that a few frames were missing inbetween the two parts
