There is a difference between a DVD player and a DVD "burner". DVD "burners" have only come as stock equipment on computers in the past 4-6 months, and only on high end "multi-media" systems. More than likely, you have a DVD player, so you can view DVDs, not write to a disc like a CDRW drive. Just to make things more confusing, they know have drives that are a DVD-CDRW combo, but they only play DVD.
As far as digital cameras go, it depends on your needs. If you plan on printing out pictures not much bigger than 4x6, then you would be fine with a camera capable of 2 megapixel (2MP). If you plan to print pictures larger than 4x6 (8x10, for instance), you would probably be better with a camera with 3MP. Of course, this is if you want the best image. You can do 8x10 with a 2MP camera, but you might start getting the little dots showing in your picture (what's called pixelation). The cost of a 2MP camera can run anywhere between $250 to $500, depending on the deal you find, and the bells and whistles that come on the camera. I would recommend looking at reviews of cameras, which you can find by doing searches on the web with key words like "digital camera review", or something similar. It helped me alot when I bought my digital camera.
