Yes, I've noticed that too, but I'm afraid I don't know if the bug is with Dreamwidth's RSS generation or LiveJournal's RSS consumption. The usernames are wrong too, where they're not the same on both sides (ewan is not the same person as ewan, for example).
Re comments: LiveJournal doesn't pass comments back to the original source of the RSS feed, and I don't think it's possible to subscribe to comments on a syndicated account, and LiveJournal only keeps RSS-sourced data for two weeks — so it's almost always best to comment on the original post! (This goes for all syndicated accounts, not just ones syndicated from Dreamwidth.)
