This question has been asked before and Mona answered it. You need to rip so many a week to get a warning. I will try to dig up and find the limit. Or, Mona may see this and reply. (DVD or Bluray, I don't think it matters.)
This is from Mona:
There is a limit, 100 per week which shall not affect the use of regular users. The count will restart every week. Please kindly try again.
