Jettman you stated in your original post that your laptop IS a "widescreen" screen.
IF you are correct, then you should understand that so-called widescreen films come in several aspect ratios, or shapes. SOME of these widescreen movies would perfectly match a widescreen laptop screen (those that are 1.78:1). But, a lot of other movies are much wider than that, and will not fill your widescreen laptop, unless you used software to stretch, or alter the shape, or zoom in, or crop.
There is software that can do all of that, of course. And, you can also complicate this by altering the display settings of Windows so that images will be chopped, or cropped.
So, to understand all of the issues, I recommend you first do a bit of quick research on the aspect ratios of films. Those who have just bought widescreen TVs are often confused when they put in a copy of "Lord of the Rings," and wonder why they still have black bars. That is because "Lord of the Rings" was shot in a "wider" aspect ratio. Then, they pop in a DVD of Jurassic Park, and for some reason it fills the entire screen, or at least it seems to. That is because Jurassic Park was shot in an aspect ratio that almost exactly matches a widescreen TV (or a widescreen laptop).
There are lots of guides to help you understand this. Here is a link to one I created:
Now, once we have that issue settled, then we can deal with the fact that SOME of the DVD playing software on computers have display options that allow you to adjust the image shape. The choices usually come down to one or more of the following:
-Stretching the entire image, so it fills your screen
-Stretching the outer edges of the picture, but leaving the middle unstretched.
-Stretching the outer edges quite a bit, but stretching the middle parts only a little bit
-Cropping (also known as zooming). This option, of course, just blows up the image so that it is large enough to fill the entire screen, despite the fact that large sections at the outside edges are chopped right off, and not diplayed at all.
Unfortunately, I do not use WinDVD5, so I cannot tell you which options it may include.
Then, on top of that, it is possible to go into the display properties of the operating system (Windows, or Mac), and choose to enlarge whatever is displayed, so that edges are chopped off. Doing this, of course, means that everything else is also "zoomed and chopped," until you go and change it back.
Hope something here is of some help...
