With the help of DVD players/recorders you can watch/record videos of high quality, play MP3-CDs, audio CDs and audio DVDs, as well as look through your photos in JPG format. DVD recorders often have an in-built hard disk on which you can record your home videos, edit them and burn them to DVD afterwards, or record your favourite TV programmes so you can watch them later. Some DVD recorders even have automatic ad recognition: simply start watching the movie half an hour or so after the broadcast started and it will skip all those unwanted advertisements for you, so you never need to watch any ads if you don't want to!
