Lossy Compression

A method of compression that sacrifices some data permanently to make the overall file size much shorter while attempting to preserve the most important data. It comes as a shock to people new to Digital Video to know that DVDs are actually under heavy compression. After using a lossy compression codec, there is no way to return to the exact source you had from your output file.

What kind of DVD's ? The retail DVD's you buy with movies on them, or is any video data written to a DVD compressed (and lost) ?
