The Intra-Hybrid Blu-ray Disc (IH-BD) incorporates a single BD-ROM layer and a single BD-RE layer so as to enable the user to view, but not overwrite, critical published data while providing the flexibility to include relevant personal data on the same physical disc.
Of course, that means you also get the straight dope with any blemishes and outtakes, but we promise they're more entertaining than your average BD-Live feature.
