Okay, thanks for the feedback. I'm really on the fence with it, but I will decide soon. Actually, I have only (1) title in my collection that only has a non-SDH track. This is Silence of the Lambs 4k. Every other title has only a SDH track or both. Did you ever come across any 4k's with only a non-SDH track?
I ask because if there are hardly ANY 4k's that only offer a non-SDH track, I would be more inclined to have my entire library all SHD. This way everything is the same. However, if there are a decent amount of 4k's with only a non-SHD track, I would be more inclined to having a mix of the two in my library. Reason being, I don't want to avoid or discard titles that only have a non-SDH tracks just because I don't want a mix of the two. Although, if Silence of the Lambs is one of the very, very few, I can just discard that one title.
