Video CD
Video CD or VCD is a way of storing video content on a CD. Video CDs are lower quality than a DVD, and can store about 70 minutes of data.
You can play a video CD in VLC by selecting Open Disc from the File menu, and selecting the VCD option. Alternatively, you can use vcd:// as a location of a file to open on the command line:
% vlc vcd://D:
or, on Linux systems:
% vlc vcd:///dev/dvd
