Hypothetically speaking, what if I wanted to make single-file digital copies of my movies to load onto my portable devices (e.g., iPad). This should be a two-step process: remove any copy protection using DVD Decrypter, then creating the digital file using Handbrake.
This process would work 90% of the time. But in 10% of the cases, when I would open DVD Decrypter, I would see this:
Look at the number of files listed at the bottom: 238. DVDs typically contain around 60 files in the TS_VIDEO folder. Look also at the size of those files: nearly 108GB. Again, the physical capacity of a DVD is closer to 8GB. If I scroll through the content window, I see that there are what appear to be multiple copies of each file. That’s how I get to 238 files.
If I attempt to run DVD Decrypter, here is what happens:
You can see that on the first large (1GB file), the progress stalls; I’m up to 5 retries at the instant of this screen capture. I tried skipping through the stalled files, but it didn’t help: the first and and the last of the feature’s .VOB files would not complete decryption.
Handbrake’s performance is variable. It failed its first attempt to even read the disk. On subsequent attempts, it seemed to scan the files (37 of them) before producing this error:
And yes, I replaced the libdvdcss.dll file with XMBC’s version, just like the forums recommend.
Windows Media Player won’t play the disk; fortunately, however, VLC Media Player does.
Question: what is the name for this copy protection scheme, and how can it be circumvented?
