cDVD discs, sometimes called mini-DVD, are regular CDs that contain MPEG-video structured in accordance with the DVD-Video specifications. These discs have a VIDEO_TS directory containing properly-authored IFO/BUP and VOB files, as regular DVD do.

Such discs must be written in the so-called Mode 1, which is compatible with both the ISO 9660 and UDF 1.02 filesystems, and therefore limits the amount of data that can be stored on an 80-minute CD to 700 MB.

By using non-standard resolutions, long GOPs, more B-frames, and high-compression quantization matrices, it is possible to store up to 2 hours of video with audio and subtitles on a regular 80-minute CD.
