Trying to download this video https://www.vlive.tv/video/152198?channelCode=E832DF throws an error. It's a channel+ video so you need an account. You can use mine but I don't know how to provide the credentials without others seeing it. This is the only channel+ video I'm having trouble downloading other videos such as https://www.vlive.tv/video/67590?channelCode=E832DF and https://www.vlive.tv/video/31799?channelCode=E832DF download without a problem.
