I've seen a few posts on this across various topics but i don't think there's been a specific topic for it.

I can confirm that the problem is still there in version 1.0.6.1.
It happens every time with some specific episodes, both on Amazon Prime and Netflix. So I've made a habit of opening the video properties in Media Player Classic HC and checking the length of the video and audio tracks. If the difference is more than a couple of seconds, I make a note to re-download that episode once the bug has been fixed.
As you can see below, the soundtrack for
Chicago Med s01e03 is 41:07 while the video is 41:38, a difference of 31 seconds!
(In some cases Netflix has very long silent end credits for many different languages. In those cases, only silence may be chopped off so you won't notice it by just playing the episodes. But the bug is still there, and can be seen by examining the properties of the file.)
