why the burned Nero DVD-R movie has glitches (square dots)?

[neutralidea]

My friend passed me a DVD movie (original). I used DVD-Shrink to copy it to local drive then use Nero to burn to DVD-R.
My DVD burner is LG.

When playing back the movie with my DVD player, I see lots of glitches in the picture (lines and square dots). During DVD ripping and burning steps, I left the computer idle and no other appl running besides the Dvd-Shrink or Nero.

Do you know the reason these glitches?

Thanks

Those are compression artifacts. They're a byproduct of compressing your original dvd (probably a dvd9) onto a dvdr. One-click products don't give you a lot of ways to tweak settings, and that's why you end up with less than a perfect copy. If you want to get better results on discs you own (hint, hint), read the ripping and compressing guides off to your left there.

Or ... if you have copied the full disk, you could try again, using Movie Only. This will help, especially if it's a long film.

Also in DVD Shrink, try the deep analysis option.

hi again,

I think what you said above was with an assumption that the movie is > than a dvd5 size. In fact, the movie I ripped had only ~3.9G all features included.
Also I saw in this forum some people discussed about deep analysis. The debate was not using this feature (not necessary) if the movie doesn't have any compression.

So still no clue...

The 'glitches' you are experiencing are also known as 'dropouts' and happen when there is unreadable or missing data from the video data stream. The player then has to interpolate the missing data and the result is the streaking and pixielation you see.

Most likely this happened in the writing of the DVD copy. It may be due to incompatibility between the writer and the media, or simply just bad media. Or your player may not be able to cleanly read your newly burned disk. So it may be a combination of factors contributed by your writer, your media and your player.

There is not necessarily a correlation between sub-standard writes to a disk whether or not 'name-brand' media will eliminate this. You'll have to try out other media to see which works best with your writer.

I experienced the same thing using some brands of media. Changing media made the problem go away.

Why are you using DVD Shrink if the movie is less than 4.7gb ?
If it's a DVD 5, just use DVD Decrypter in ISO/Read, to rip and ISO/Write to write.
If someone is using DVD Shrink, it's reasonable to assume they are working with a DVD9, so maybe a bit more detail in your posts could avoid misunderstandings
Clearly there is no need for Deep Analysis on a DVD5, as people wouldn't normally be using DVD Shrink for these.

Given your new information, I would agree with the last post. Try using some Ritek disks .... these are known for their compatibility & reliability.

hi all,

Maybe you are right. I used the same brand name, but just changed my media from 1x to 4x. It was no problem with 1x (sometimes having dropouts in the movie), but it happend more significant when I use 4x.

I guess that would be my DVd player which doesn't support the 4x format for some reason. I tried to burn another movie < 4.3Gb to 4x media [using TMPGenc DVD Author writer], but my dvd player still displays glitches.

With these 2 movies burned, I tried with another player from my friend's house and they seem both no problem (no glitch).

I will try to go back to 1x media to see....


To Thomas: I was using DVDShrink to rip the movie from the disk. Of course I used "no compress" selection.

Thanks

Sounds like your player is having trouble reading your burned disks.

If it is an older model, it is possible that the laser levels and player sensitivity have changed as the machine has aged, or gone out of adjustment. The laser and the sensing mechanism may not be able to solidly track and sense the DVD-R as consistently as a manufactured DVD.

Take your burned disks to a DVD retailer and try them on a variety of machines. If they play well, then it is likely that your player needs adjustment or replacement. In any event, you won't waste time trying to fix the burn process when it is the read process that is at fault.

This sounds like a bad media problem. I don't use Riteks (Taiyo Yuden is my preferred brand) but if you spring for them, get a good source recommendation from one of the members here.

fluffster has good advice as well.

The "glitches" you see are caused by Nero's built-in "pirate-block" that detects when someone is copying a video they don't own. Very common. If you go buy the movie yourself and quit copying your friend's, then it should work just fine.

[classfour]

I knew there was a reason not to use Nero on backups....LOL



The DVD Decrypter method is by far the easiest and fastest for making an exact backup of a DVD 5. My $.02

i was having this same prob - get the 3.6 version (i think it is) of dvdshrink - the new one that just came out - in the log file it says it fixed that problem - i was using ritek and cheap media and they both did it - after i did that it started working -=]

God yeah .... I clean forgot about Nero's built-in "pirate-block".

It has to be that for sure.

[neutralidea]

I finally did a test now...
I burned the same movie (with compression now) with Nero on 2 different medias (both are 4x). The princo is giving me glitches but not for Riteks

I selected "deep analysis" when ripping dvd with dvd shrink... 8) .. but still glitches. Now it proves that the media is a problem for me...

[lordsmurf]

hHis has nothing to do with Nero. It is likely bad media.

[PhreakPhish]

i had sandy yang and ritek - both did the same thing - i found out that it was dvdshrink - like i said - get the new version that just came out and yuor problem will be solved - also use region 1 - not region free
