"VCR" was short for "Video Cassette Recorder", a device that recorded analog video on tape cassettes. When digital tv came up in the late 1990s, it was only natural to record that data on computer harddisks instead of cassettes. So, in the year 2000 the very first steps were made into programming a "VDR", which stands for "Video Disk Recorder"...
