If your DVD
skips, freezes or won't play,
always do two things before contacting us:
1. Try cleaning the DVD disc. Even a single finger print
smudge may cause a problem on some players. Here is how to clean
your DVD disc:
If you experience problems when playing a disc, try to correct
them with a simple cleaning.
Do not use strong cleaners, abrasives, solvents, or acids. With
a soft, lint-free cloth, wipe gently in only a radial direction
(a straight line between the hub and the rim). Since the data
is arranged circularly on the disc, the micro scratches you create
when cleaning the disc (or the nasty gouge you make with the dirt
you didn't see on your cleaning cloth) will cross more error correction
blocks and be less likely to cause unrecoverable errors.
Don't use canned or compressed air, which can be very cold and
may thermally stress the disc.
For stubborn dirt or gummy adhesive, use water, water with mild
soap, or isopropyl alcohol. As a last resort, try peanut oil.
Let it sit for about a minute before wiping it off.
There are commercial products that clean discs and provide some
protection from dust, fingerprints, and scratches. CD cleaning
products work as well as DVD cleaning products.
If you continue to have problems after cleaning the disc, you
may need to attempt to repair one or more scratches. Sometimes
even hairline scratches can cause errors if they just happen to
cover an entire error correction (ECC) block. Examine the disc
to find scratches, keeping in mind that the laser reads from the
bottom. There are essentially two methods of repairing scratches:
1) fill or coat the scratch with an optical material; 2) polish
down the scratch. There are many commercial products that do one
or both of these, or you may wish to do it yourself with polishing
compounds or toothpaste. The trick is to polish out the scratch
without causing new ones. A mess of small polishing scratches
may cause more damage than a big scratch. As with cleaning, polish
only in the radial direction. Libraries, rental shops, and other
venues that need to clean a lot of discs may wish to invest in
a commercial polishing machine that can restore a disc to pristine
condition after an amazing amount of abuse. Keep in mind that
the data layer on a DVD is only half as deep as on a CD, so a
DVD can only be repolished about half as many times.
2. Try playing the disc on another player. Even if all
your other discs play just fine on your DVD player you still can
have problems with certain disc. The only way to know if the problem
disc is defective is to test the problem disc on another player.
Never assume that because your other disc plays fine, the problem
must be the disc. About 90 percent of all the discs sent back
test just fine, so always test any problem DVD on another player.
Premixes don't
work or have problems?
If the normal program plays fine and you are only having a problem
with your premixes, then the problem is with your player. A premix
is just a computer script that tells your player what to play
next. It is impossible to not have a problem with the regular
"Play" program and to just have a problem with the premix. When
this happens the problem is with your DVD player's firmware. We
find about 3% to 5% of DVD players will have some problems playing
premixes. In most cases the problems are minor, but in others
the premix will not play at all.
