Hybrid SACDs, DualDiscs and DVDplus are tricky formats, because they have two different layers. The layers should often have different tracklists, because they have extra tracks in one side, or because the recordings are different on each layer (stereo vs. 5.1, audio vs. video are usual differences).
Right now, a lot of Hybrid SACDs at least (I have little personal experience with DualDiscs/DVDplus) have been entered as just one medium, without differentiating between the sides. The proposal would be to always add a medium per side, and adding "pseudo-formats" for each format that can be used to specify which side is which:
- Hybrid SACD (CD layer)
- Hybrid SACD (SACD layer)
- DualDisc (CD side)
- DualDisc (DVD-Video side)
- DualDisc (DVD-Audio side)
- DVDplus (CD side)
- DVDplus (DVD-Video side)
- DVDplus (DVD-Audio side)
There was some strong opposition back when this was discussed. The main argument was that having multiple mediums for what is actually just one disc is confusing, and suggests that the release has multiple discs. While I agree it can be somewhat confusing, I feel that the benefits outweigh the drawback, but I'm curious what other people think.
Other suggestion was to wait until we get format attributes (MBS-3993). That hasn't happened for years though, so I think it'd be better to do this for now, and transfer them to attributes if and when those get added.
If you have any suggestions on better ways to do this, reasons why it's a terrible idea, or anything else to say, feel free to add a comment. Even if you don't, do vote and say what your preference is!
- Add the "sub-formats"
- Wait for format attributes
- Just don't do this / do it differently
