Perhaps someone here can explain the following. When I view a DVD on my PC, some DVD's especially in dark scenes, if you look carefully, you can see large blocks of solid colour moving about. Not sure if it's what you call mpeg artifacts or what, Like in a scene where someone is in a cave. If you look into the blackness, the black is made up of large areas of browns, dark greys etc. they move about with the movie. Now I have always notice this on PC playback of a DVD. I have upgraded my CPU and tried 3 different software players, I even changed graphics cards (from a matrox to a voodoo) and I still see these. Even when playing DVD's on the TV Via an Xbox I can see this kind of thing happening (well it's a PC isn't it) The thing is. I don't recall every seeing my real DVD player showing these blocks of colour. Almost as if it has special ciruitry to smooth these patches of colour out...... I'm not alone in this as I brought this Xbox and bocks of colour in dark scenes and others also said they had sometimes notice this too. But, we are all saying how a HTPC gives the best image quality. So now I'm confused............... Can anyone explain what I'm seeing and what they do about it ? Is it down to graphics cards, and changing to a Radeon will stop the issue? I'm just puzzled right now as in the past (until I read about HTPC) I would have said a real DVD player was better.
