I'm a little worried that there may be something wrong with my new JVC-S60BK DVD player. But the question applies to all players.
Is pixilation common with DVDs? I've noticed on a few discs a high amount of pixilation at times. By no means is the effect always occurring, and it looks like the data bandwidth is lower when it occurs. I know that DVD production companies have to pick and choose the resolution, based on the amount of detail or movement required in a scene, but sometimes it looks really bad.
For example, during the movie "Blade", at around the 35 minute mark, there's a scene where the heroine is packing a suitcase. The gray wall behind her is alive with large pixilation - big square blotches which vary in hue from frame to frame. Does this occur with all players, or just mine? Anybody with the movie want to check it out for me?
I've messed with various picture settings, such as sharpness, gamma, contrast, brightness, both on the player and the TV (where applicable), and all I can do is change where the giant pixels are noticeable. There's no setting which "cures" the problem.
I've also tried viewing with interlaced and progressive settings - no difference at all.
I've seen the effect quite regularly on many dvds. It manifests itself as "shimmering" on walls and such. It's like the pixilation described above, but the squares are much smaller. It's usually move evident when there is a uniformity of colour over most of the image, and only subtle differences from area to area. Are these types of scenes more likely to have a lower bandwidth assigned, given that many TV's won't distinguish the subtle differences all that well?
I need help in setting my expectations on what I should be seeing.
Thanks,
Martin.
