No, I’d just committed to learning how to use multiAVCHD in the hope of swapping in the DTS. Much to learn, I still have.
And at this stage i still favor film and extras on one epic 50gb disk. I can’t include all the audio and subtitles from the MKV as that would not work with Encore’s structure so this will always be a companion to the official MKV. Thus, there should be plenty of room for special features on my 50gb disk.
But as others have said, video and audio quality of the films is the priority here.
