Memorex CMCs

[richdvd]

When I first started burning, I used to buy Memorex media because I didn't know
how bad they were, and they were very cheap and easy to get a hold of.
So... I Just took 5 Memorex DVD-Rs (4x) out of my collection for testing through DVDInfo (none of them had any marks on them at all).


I tested them on a Pioneer 107D and a LiteOn DVD-ROM.
All 5 of them produced at least 26 read errors. One of them actually gave me 135!
These discs played fine on my Stand Alone DVD Player.

So I decided to copy 2 of them to Maxell DVD-Rs.
I then ran the Maxells (copied from the Memorex) through DVDInfo and there wasn't 1 read error. If these Memorex have so many read errors, how come I can copy them and play them fine in my DVD Player? Are the Memorex DVD+Rs any better? I will never go near CMC discs again. I just never really realized that they were as bad as this! WOW!! That was just 5 that I chose at random too.

I wonder what all the rest in my collection are like.

If you copied from disk A to disk B, why would you presume that it is "good" media versus "bad" media?

When I set Nero to copy a disk, I check "
Ignore Errors", and the like. Why would it copy and check as errors in your proofing program? Why would you think that the copy of that terribly error riddled cheap ass disk would automatically be repaired because you put it on a "good" disk?

You can copy anything to a disk. Corrupted files will be an exact copy. The setup will not be able to run, but the file will be a bit for bit copy.

Corrupted, and here I use the term loosely, video files, will be copied bit for bit, and if the disk plays badly, your proof program will say "100% error free, so sorry the DVD won't play".

Maybe you should print and file the test result and come back in another 6 months and see if it is worse. Then you "may" be able to connect the two, Yeah, the disk is failing.

Hey, if it plays in your machine, that is all that counts, as it IS a backup, is it not?

Cheers,

George

Read errors vs NO READ ERRORS

Because I ran it through DVDInfo Pro 2 times through 2 different drives.
I didn't say that it was a terribly error riddled cheap ass disk.
I said it had several 'read errors' on it.
The Maxell shows ZERO 'read errors'
The Memorex it was copied from shows several 'read errors'

Corrupted files will be an exact copy

I didn't say corrupted files.
CAN'T YOU READ ??????

I said the discs played fine.
I am talking 'read errors' in the program DVDInfo Pro.
Do you know what that software does?
I suggest you look it up.

if you are trying to start an arguement, it's not going to work.
i simply posted my results from some tests i did today for others to see.

Memorex CMCs. Been there, done that.

Luckily, I have a trio of Optorite DD0203s, and they won't burn anything correctly if they don't like the media real well. They like to give those Memorex CMCs the ol' Power Calibration Error, and that's a sure sign of shit media.

I guess the question is, how much of a problem will the read errors actually cause? Are these errors that the Reed-Solomon scheme will correct or are they enough to crash the playback device in question? Don't know on that one, but I suspect that if they play fine in spite of the read errors being reported, RS still has the upper hand.

Memorex +Rs that are made by Ricoh have been fine for me. These are the garden-variety Wal-Mart Memorex jewel-cased discs with the purple liners. I haven't purchased any in awhile but the last batch I got was still Ricoh.

Indoliika,

Don't encourage him.

The boy is copying a "corrupt" file, a DVD that the check program said has errors,and expecting the copy to also have errors, or to have entered data to the file to correct the errors.

Since the "new" media, the "good" media, copied the file with the errors intact, and checked as 100% in the proof program, this jerk thinks that his new media is superb, as it will correct glitches in a coversion.

One bad bit in a data file, a set up program, will crash the set up. "Corrupt Data".

One bad bit, or 26, or even the 150, or whatever, with the data correction of DVD MAY cause a glitch, but probably not.

Get THOUSANDS, lad, like some here have wailed about, then you may bitch. .Just don't carry your other posts over to all others about media and bitch about them.

Elsewhere, you tell people this is crap media, you get challenged, you respond that you didn't say THAT, you get challenged again, you go elsewhere and start the same shit all over again.

Wise up, lad, read a little, learn about this stuff before you start to pontificate. You ain't the Pontif.

Cheers,

George

Read errors vs NO READ ERRORS

I shou;d have copied your smart assed remark. You have copied a disk with a flaw or 2 and you think the copy program should or did correct the original error? Get real, lad.


I didn't say corrupted files.
CAN'T YOU READ ??????

A read error is a corrupted file. DVD error correction can overcome that.. Have you at least the basics of this stuff?


I said the discs played fine.
I am talking 'read errors' in the program DVDInfo Pro.
Do you know what that software does?
I suggest you look it up.

That is the worst thing you could say, the disk plays fine, but I read it with a proofing prog and it is a mess, so that is Grade B, C, D, or even off the scale media, it must be garbage, just like the stuff you railed against in the threads where you were asked to give some specifics..
I am not following your threads, but you are sure as hell trying to convince people to use just YOUR brand of media with the worst arguments I have ever heard..

Cheers,

George

richdvd When you gonna learn to think before you "TYPE in this forum. I still think you're a funny guy to laugh at. In one of your other postings you said you burned over 100 CMC discs and had no problems with them. Now I see you've found errors on them but they playback fine. As I've stated numerous times that if a brand of media works for you, it may not work for others. If the burned disc works in your standalone dvd players that is all that matters. But hey I'm no expert I just state my opinions based on my own experiences in creating backups of my dvds and with the help of others in this forum site.

Funny that your ugly head pops up to take a shot at me.
Where were you in the other forums when everyone else was saying how crap your favorite media was? You somehow disappeared.
I noticed that you changed your avatar too, after that Ritek thread.

That is the worst thing you could say, the disk plays fine, but I read it with a proofing prog and it is a mess, so that is Grade B, C, D, or even off the scale media, it must be garbage, just like the stuff you railed against in the threads where you were asked to give some specifics..

I agree, CMC is bad media and I never said it wasn't.
Specifics..... why would i waste my time?

I am not following your threads, but you are sure as hell trying to convince people to use just YOUR brand of media with the worst arguments I have ever heard..

LOL No Actually, I highly suggest that people stay away from CMC.
I am not aguing with you, as I said before.
I am just stating some facts based upon my results.
If you don't believe it, I could care less.

[jntaylor63]

Well, I'll take the other side of the story.

I have burned 10 of the Memorex DVD-R's that are CMC's without issue. I can play back in my new Pioneer CV-D505 an in my old Panasonic A-120. (and that one can't play back hardly anything home made!)

There is a lot more look at when you get bad play back problems:

1.) Your burner
2.) Your player (Standalone / PC Driver and its software)
3.) Your software to write the disks.

Like others have said, if it works with your gear the great! If not, find something else. When you start with a new brand, buy just a few and test it out.

[richdvd]

i would bet that if you ran those through DVDInfo Pro, you would find some read errors like i did. Like i said, the discs played fine for me in my Stand Alone and 2 PC DVD drives. I don't know how DVDInfo determines read errors but they sure aren't corrupted files. If they were, the DVD wouldn't playback properly. I am kind of baffled because I copied the Memorex with 'read errors' to a brand new Maxell DVD-R 4x using DAO and the Maxell produced no 'read errors' in DVDInfo.

hmmm little man richdvd....I'm still laughing at you.....you seem to forget easily that others have bashed you for putting up your crap threads in here....wake up little man....you whine and bitch about having errors on CMC memorex media...then you back down because people like Laceywest and George shot you down....as for me disappearing from the Ritek thread....I said what I wanted but you call that disappearing....
LMao! I won't get down to your little man mentality....your postings in here are worthless ...continue to speak your feeble little mind and I will continue to laugh at you as I've always done.

[richdvd]

you whine and bitch about having errors on CMC memorex media

Not whining and bitching at all.
For the 3rd time, just stating some test results.

as for me disappearing from the Ritek thread....I said what I wanted but you call that disappearing....

You are the type of little bastard that if you see a gang you will join it, such as jumping into this thread. As soon as a few other people said something...here you are again. You can laugh all you want....
I know you are still crying over all the people that bashed your shitty orange Riteks...You are mad at me because I thought they were Grade B.
Big f@@kin deal pal.

[mr. anderson]

your postings in here are worthless

yours are 2

[nickelzy]

This kind of ranting back and forth is what makes forums that are unbelievably helpful and of tremendous value to most of us go to shit. People tend to take these things so damn personal - it's like their discs are their children. You better not insult my disc or I'm going to flame you!! Man, I get sick of it, but I stick around because through bullshit like this, there is a TON of other good stuff.

Ok, I'm done, I feel better now. Now you two can carry on if you'd like.

I totally agree with you.
I was just trying to help others out with what i have found.
And then 2 idiots have to come in here and raise hell.

Rich,

Try to understand this.

If you burn a DVD and the data is 1, 2, 3, 4, 5, 7, 6, 8, 9, 0, and run it through a proofing program, it will see read errors at 5, 7, 6.

If you then copy that disk, same series of numbers, ( data.) will proof as a "good" burn, because it is exactly the same as the stuff you copied.

If it were a data disk, it would not install, or whatever the disk was.

As a DVD movie, error correction would try to overcome it. If the original, with 26, 50, 150 errors, played, the copy will too, but proof program will not find the errors that the original showed because it is a true copy of the "corrupted" disk.

Your checking program is looking for badly burnt "spots", not for a bad frame. It is not going to run a 2 hour movie in 10 minutes and say "Frame XXX, and XXY, and XXZ are bad." It's going to tell you it expected to see a 1 or a 0, and found neither

Cheers,

George

Good explanation.
This is what I didn't understand.
Thanks

badly burnt "spots",

so obviously these don't get copied over to the new blank disc......correct?
