Yes, it probably takes a while until it's been distributed through IPFS.
I've heard, that dTube videos tend to disappear after a while, because the server capacities are limited. When you use dLive, you will also get the full rewards, while dTube takes some percentage of your rewards.
Don't know exactly, how it is with dSound... (so many options).
I better try them all out to see which one fits me best if it again becomes necessary to explain Swedish words.
