I implemented that as a result of a request. Not all discs have DTS-MA or TrueHD as a choice, and they wouldn't necessarily have the same audio content as the LPCM. There are also discs that have only LPCM (like some concert discs). But most importantly the concept is to have a choice to "Keep HD, unless it's LPCM", because LPCM is so wasteful. That way you can set it and forget it. By the way, note that it only applies when you have also selected "Keep HD audio for BD-25".

Of course you can drop it if you want just by deselecting the track.

To keep only the main audio and drop others -- in the SETUP dialog just say to leep only "English" (for example), and also click "Limit to one track for each Language" -- that way it would only keep the first English track.
