Most DVD movies that you buy or rent are recorded on "dual layered" commercial grade DVDs. These types of discs are known as "DVD-9" discs and they can hold up to 9 GB of data. Blank DVDs that you buy to copy movies are "single layered" and can only hold 4.7 GB of data. This means that in most cases, to fit a movie onto a single disc (which holds half as much data as the original DVD), you must either remove some of the extras (trailers, directors cuts, extra audio languages) or compress the video to make it all fit on a single disk. DVD movies are already heavily compressed when you buy them. By increasing the level of compression by a small factor, the whole movie can easily fit on a single DVD and in most cases you will not see any difference compared to the original. 1Click DVD Copy will allow you to back up your DVD movies and gives you the flexibility you need to keep what you want. You can copy just the movie with the menus intact or include the extra features - the choice is yours. |
