I play DVDs from my HTPC's Hard Disk (ripped using DVD Shrink) through Theatertek and via a VGA connection to the Plasma. My problem is that in some films I notice a very bad effect that makes parts of the screen look like the picture has been made up of distinct seperate blocks of colour giving a 'Painting by Numbers' impression! Two films that show it the most are The Hulk and Master & Commander, which is because the effect appears mainly in sky, dust or fog scenes. I have tried to take some screen shots (via WinDVD) to show the problem but I should point out that, though still visible, the effect is not as distinct as when the film is playing. The films (both PAL versions) were played with the Powerstrip set to 1368 x 768 at 60hz. I've put the post initially in the Plasma forum as I'm wondering if it is a Plasma problem but it maybe that it should be in the Computer & Home Cinema PC Forum. Anyway have a look at the pictures - 45degrees above and to the right of the Hulk and in M&C, look at the fog to the right of the picture. Again, I would stress that it is worse than these pictures show (and they're pretty bad)! So, does anyone have anuy ideas?
