I copied over The Incredibles 2 as an ISO to my hard drive to eliminate actual disc issues. When ripping to mkv using nvidia (CUDA) I only get 16fps (usually I am on around 150-200) and all the input ptrogress bars are at 100% (usually towards 0-10%). Then trying the preview player it keeps hanging the whole CloneBD application and I have to kill it. As soon as I try anything there, like switching track or forward it hangs. Not sure if it's related, but could be. Anyway, just thought I share in case it is an issue.
