distortion problem in playback of DVDs
showing a lot of distortion, like lines of squares across the screen. The same disc will play okay on some machines, but screw up on others. Cleaning the heads with a brush stlye disc cleaner seems to help for a little while sometimes. Sometimes running water over the disc then wiping it dry will help. Is it a static electricity problem? Or is there dirt on the laser that the brush won't get off? Or a combination of such things? Is it possible to open a DVD player and clean the laser, like we can do on a VCR? Or is the best thing to replace a DVD player when it won't play discs consistently any more? Thanks for any help! David d@. wrote:

with discs looking bad, or playing back badly. Recently I've been having a good bit of problem with playback, and have noticed that even the latest discs have what appear to be spider web size lines in them. Are they scratches? They don't really look as much like scratches as they do maybe cracks, to me. And the older DVDs that I recorded still don't have anything like that, even after years of use. Are these newer discs of much lesser quality? What should I look for in order to avoid such garbage in the future? My machine uses DVD-R. Thanks for any help!

Would the poor quality discs work okay in a new recorder? Would they also work okay in other machines during playback? On Wed, 08 Feb 2006 14:02:42 -0500, d@. wrote as underneath my
scribble : You are mad if you waste time with DVD blanks that have anything visible wrong in the active layer, when even invisible faults can easily arrest playback, the error correction isnt that robust. Return them to the mfg immediately. I also always inspect the disk after burning as a weak/thin patch(es) in the active layer sometimes only show up after burning. I have recently come across some DataWrite 16x disks in multipacks where there are faults in this catagory. I get the impression that quality control from the mfg plants is not quite as good as it was. Complain! -It may help us all!

The best way to clean a CD or DVD drive is to open it up an clean the lens with glass cleaner and a cotton swab. I use Glass Plus because I have read that some drives use plastic lenses and you should not use ammonia on plastic. I have resurrected many old CD drives this way. I have not had as much success with DVD drives because they usually are not very dirty and the problem is elsewhere.

Unfortunately the actual curves are all trade secrets! So your only recourse is to record for yourself (and the rest of us???) which make drives work how well with which make disks. Burn at possible the lower speed. High speed is good when you play disk on
computer. When you play at home DVD player that's when problems begins.
