1 1. Whats New? Chapter 1 - Whats New? The popular fifth generation Sony DVD players introduced for the years 2\ 001 and 2002 are physically and electrically different from previous generation players; they have great\ er appeal and are lower in cost. Physical Differences The single disc players are thinner than the previous fourth generation \ models and take up less vertical space. Some models are available in both black and silver (same model number)\ to blend with different decors. Two models, DVP-F25 and DVP-F41, have slot type loading (like a car CD play\ er) which makes them smaller; they can also be played horizontally or vertically; a pedestal base can be at\ tached to the side for vertical mounting, as in Figure 1-1.
