I cannot rule this out as the true source of the problem. I know that educational material is sometimes copy protected in unusual ways. Have you considered the very real possibility that If anyone can think of anything that might help, or a player like VLC that wouldn't have this problem but would also record.
I wish that wasn't so, especially since I wanted to get a decent copy of the material for playback. The WMP playback is so smooth with these odd discs, but VLC is having a real problem with them. I'd hoped to use VLC to create a "no annoying icon" version of the DVDs.)Ĭan you think of any reason why the VLC player stutters and chokes at such points, but Windows Media Player does not? (VLC stutters at those points in the playback whether I'm trying to record or not.) Windows Media Player also does not have the ability to RECORD the DVD playback to my hard drive. Windows Media Player does NOT have the stuttering problem at such points. but the VLC player chokes up and stutters (and sometimes skips a few seconds) as the lettering is about to appear. If I play the DVDs on my computer using VLC, the icon doesn't appear (thankfully).

The problem is, any time they flash printed words on the screen, every DVD player I've tried displays the "alternate scenes to choose from" icon on the TV screen. Depending on what language you choose at the start of playback, you'll hear the audio and see the onscreen printing in that language. They have eight different language tracks you can choose from, and any printed words onscreen (including the title of the DVDs and different sections of the material on them) are also in each of the 8 languages.

VLC will do the authentication handshake process and therefore you are free to copy the files of.I'm using some DVDs that were made in a very complex way. A player would execute an authentication handshake with the drive (again based on specific keys) to make the drive pass those blocks. The drive blocks access to logical blocks that are marked as protected. This is also not the issue you are hitting here. The player decodes the video on play time by getting a key block from the DVD and having its own key and decrypting the video data. As you can play the DVD in a media player, this is not the issue you are hitting here. This is a drive limitation and has to be circumvented by getting a suitable drive. The drive can deny access to the DVD if the region on the DVD does not match the drives region.

So let me sum up the background of the "issue" you are facing.Ī generic movie DVD has three protection layers (part of the "Content Scramble System" or CSS): I am aware that this question is pretty old but it still has some hits via the search engines.

If you are playing a copied directory of files, you don't have access to the IOCTLs to get the keys, so libdvdcss resorts to statistical cryptanalysis to crack the encryption.) (Interestingly, the DVD IOCTLs are also the only real way to get the decryption key used to decrypt the data on the disk, once you've read it. Once it's unlocked, the drive can't tell which program is reading from it, so it sends back the (still encrypted but now readable) bits to anyone, including dd or cp. Presumably a standalone program that linked against libdvdcss could be written to unlock the drive for access as files, instead of relying on all of VLC.
VLC performs this secret handshake through libdvdcss, which in turn seems to do it in GetBusKey() in css.c.

More information on how these IOCTLs work is available in this mailing list post from the person who implemented them, but basically they provide a way for userland software to perform the secret handshake with the DVD drive hardware. That's why this manifests as an I/O error.
So it's not just that you will get encrypted data that can't be played if you read the DVD the drive won't send back the bits unless some program on your machine has authenticated itself to the drive, using some DVD-specific IOCTLs exposed by the Linux kernel (in this case, DVD_AUTH). The player has to execute an authentication handshake It denies access to logical blocks that are marked as copyrighted However, if the drive detects a disc that has been compiled with CSS, The underlying cause of the issue is that your DVD drive is working against you. This sort of magic offends my sensibilities, so I went digging. It didn't work, unless I first opened the DVD with VLC, at which point Kodi could magically play the files. I managed to replicate this behavior when trying to play a DVD in my computer from a Kodi device hooked up to my TV, by using SMB to share the root of the DVD drive over the network. People mention that opening the DVD with VLC (which displays the DVD menu) magically makes the data accessible to dd, but nobody has yet explained why that is and how VLC accomplishes this feat.
