Next, technical aspects. If the user is still determined to find a digital copy (assuming they have the right to do so, like a personal backup), I can explain what WebDL is. WebDL is a digital copy of a movie that's been downloaded from a streaming service before it is made available on physical media. However, downloading it without permission is still illegal. But in some countries, there are exceptions for personal use if you own the physical copy. Since this is ambiguous, I should avoid providing steps that might enable illegal downloads.
