Getting a CRC check when I try to rip one of my DVDs.

I'm assuming its one of the several blemishes/scratches I can see
on the surface.

Has anybody been successful in rubbing these things out or
getting rid of them some other way?

I've tried 3 readers and two DVD players. Nada.

It's sounding to me like I just need to suck it up, go down to
the local used DVD store, and buy another one.

Try it on a old CD first.... use a clean soft duster and metal
polish.... the fluis stuff not the wadding!!!

The data is burned on the inner side between the label and the top
cover the underside which acts as a mirror to reflect the return laser
beam onto the sensor.

Sometimes the top label can get damaged or scratched so that it will be
reflective 'no more' in this case it's all down to experimentation.

The surface is purely protective deep scratched can be got out but with
plenty of rubbing and patience - the secret is to use a circular motion
over the entire disc... or at least abraid the surface down equally so
that it doesn't become concave - looking likje a telescope lens.

Do not attempt to use the wadding variety like Duraglit this tends to
leave minute microscopic scratches under a bright light although
'usually' causes no problems.

The polish I use is either Brasso or Silvo doesn't matter which - the
secret is rubbing, plenty of it in a circular motion...... wait for
it....

Are you waiting? Toothpaste will also do the trick and may well be a
better choice as it's not as course as metal polish.... Don't believe me
see this clip!

Obviously for deep scratches I'd start with the metal polish and work
down wards.

This includes placing them on a surface.

There are only two valid places for a DVD or any optical data disc,
especially the new HD formats as HD DVD and BluRay DVD formats.

The best optical surface is the one that has never been touched or
cleaned.

1200 grit jeweler's rouge and a lot of luck might get you the surface
quality you need to recover from lost data blocks.

Some things go beyond what the error correction can manage on playback.
"Ripping" usually requires a more complete, error free datagram.

That should have been your thinking as it relates to all of it. You
should be picking up a nice, new PS3, and the BD version of the film.

My local DVD store actually offers a service to polish your own DVDs for a
couple of dollars.

A very gentle cleaner (yes, toothpaste can do the trick) and very very
soft cloth of the sort used to clean eyeglasses can often do the
trick.
However, NEVER clean in a circular motion as an earlier poster
suggested. That will destroy most discs. Cleaning must always be done
in straight lines from centre to rim.

I'd be wary about using toothpaste. Some of them are very abrasive.

Jeweler's rogue can be bought usually from any hobby store or supply
site.

It is really simple to do it right.

Well, while we're throwing out crazy ideas here, might as well throw
out one of the craziest... ever heard of boiling a disc?

I'd read it online somewhere and was skeptical, then tried it on a
couple discs I had around with minor-looking scratches that wouldn't
rip...and damned if it didn't work. For one of 'em, anyway - no go on
the other. I've tried it a few times since and the success rate is
pretty much 50/50, sometimes it does the trick, sometimes not, and if
the scratches are big, it probably won't do a thing.

I admit it sounds stupid, but just boil a pot of water and toss the
disc in, play-side down. Let it sit for a couple minutes, take it out
and dry it off and see what happens. I've never had any discs melt or
otherwise get screwed up, though I don't know if one would want to try
it on a DVDR/CDR.

And for the really difficult repair jobs -- download from internet the
free program Exact Audio Copy (EAC). I've used this to do flawless
digital rips of discs that none of my standalone CD players could
navigate -- perhaps because EAC is programmed to try to get data
several times from damaged arrors. I then simply burn a replacement
disc and throw out the original. Just had to to that in a six-disc
Billie Holiday Complete Verve Master Studio Takes edition -- the
original was badly scuffed and wouldn't play; my replacement copy is
perfect in every way.

Here's my sequence of dvd rehab techniques. I've used these
techniques literally hundreds of times.

1. I apply a few drops of STP "Son of a Gun protectant" rub it over
the surface of the disk and let it sit for a while. While I have not
used ArmorAll for this, they appear to be similar/same substances.
Wipe/remove/dry with a soft bit of cloth and give it a whirl.

2. If that doesn't work I spray a little bit of WD-40 on the disk,
rub it around and let it sit. Then I gently wipe/remove with a soft
cloth. I leave a thin sheen of WD-40 to "bridge" the scratches.

2.5 If these still don't work, I coat the disk liberally with either
of these and leave overnight. Then try again. I'll put an STP'd disk
into a closed case so it doesn't dry up.

3. If still no joy, I'll use toothpaste then rinse off and coat with
either STP or WD40. An ancient tube of Colgate Baking Soda and
Peroxide has some nice tooth to it and levels out some fairly bad
scratches, then the STP or WD40 fills in the new, smaller scratches
and I get my read/rip.

Now if you have access to a real, commercial grade disk polisher,
that's the way to go.

100% agreement on that.

The rub comes when somebody doesn't center the DVD in the drive
tray and the tray tries to pull it into the device.
