GeForce DVD Tweak Guide

"In software DVD Decoding, the digital video is processed through a technology called Hardware Overlay."





The GeForce has is very well known as an all around well performing video card, its DVD performance is no exception. Armed with its own hardware Motion Compression, it takes some of the heavy DVD decoding load off of your CPU allowing smoother playback and less stuttering on lower end machines. The DVD Image quality, while exceptional on the GeForce, can be tweaked to look even more vibrant. After all, that's the whole point of the DVD technology.

How it all works

In software DVD Decoding, the digital video is processed through a technology called Hardware Overlay. This hardware function on the GeForce (and other recent video cards) allows the DVD to be drawn on a new "layer" over the previous screen. In most software decoders, this is done through a DirectX function, DX Overlay. The new layer has its own set of onscreen settings, separate from your desktop. This means that all of your gamma, brightness, and contrast tweaking, will no longer apply to the DVD movie being played.

What you need

  • A GeForce/GeForce2 Card
  • P2/K6-2 300+ (400+ preferably)
  • DVD-ROM
  • Any good software Decoder
