HD audio track question

[sliu2005]

after BD disc analysis, makemkv showed a "DTS-HD Lossless English" audio track, along with a child item "DTS 3+2/1 English", which is the DTS 5.1 core. My question is, if I only want DTS-HD, should I check both, or just check DTS-HD? if I check both, VLC shows two audio tracks, does that mean makemkv extracted DTS 5.1 and added back to the mkv file, thus increased audio size? let's say original DTS-HD consumes 3GB storage, of which DTS 5.1 core uses 0.5GB. so if I check both, the result mkv file will have 3.5GB audio, is my understanding correct?

just check DTS-HD?

This.

This.

thanks for the reply. It is still nice to know whether check both would increase file size. if yes, then I will always check HD audio only. If no, then it is better to have both because some players or codecs are not compatible with HD audio tracks. any ideas?
