Backups brighter than originals?

[midimidi]

I don't think I've seen any info on this at all.

I've backed up well over 50 dvd-r's now, each slightly different from the other, but I have a fairly firm grasp on the whole process now, and generally use imgtool->Nero6, DVDXCopy, or DVD Decryptor for burning.

Has anyone else noticed a considerable difference in 1:1 backups vs. originals? Using either Nero as my burning or DVDXCopy, I have quite a few dvd-r's where the backup clearly looks different - the only way I can describe it is "brighter," and do to this brightness, a loss in quality of color and pixelation.

My best example is Dusk Till Dawn, right at the Dimension logo. You barely can notice it at all playing back on a computer, but on a TV, its clear as day. This logo in general has serious pixelation, both in the original and the backup, but the backup brings it out a ton more (thus how I found it). When I brighten up the TV (or computer monitor) I can see it just as well with the original, but not as easily on default brightness/contrast. This comparison was seen on 2 dvd-roms, 2 monitors, 3 dvd-players, and 3 televisions.


Has anyone else seen this? Is there any information on what programs produce it? Unfortunately, I can't remember the exact process for every DVD I own, so I may just have to record that kind of data from now on.

Thanks a million...will take a screenshot when I get a chance...

bump - anyone notice this horribly annoying effect?

If you are doing 1:1 backups like you say..then the original isn't compressed at all, therefore, it shouldn't be DVDXCOPY which is causing this. However, if it isn't an original version of DVDXCOPY....then anything is possible...that would then be at your own risk. If the copy is authentic...then the highest probability would be 1) your media, or 2) your burner.

Lower quality media seems to allow for pixelation. A poor burn may cause this as well. But more likely then not..it's the media. As far as the "brightness" issue goes...again....DVDXCOPY won't touch the original...as far as compression/transcoding goes...because you are doing 1:1 backups..and therefore put dual layer movies over two disks.

Take an original disk where you notice this issue...copy it to some DIFFERENT media..other then what you are currently using. Try to get some TDK +R disks or Maxell if you can...or burn it to a high quality RW....then see if the pixelation and brightness issues are still there. If they are still there with higher quality media...then you may want to look into your burner causing this....followed by DVDXCOPY.

I've been using Ritek's for all my burns - R03 and R04 - though I'll try again with Dusk Till Dawn.

What about DVDShrink, choosing uncompressed? Is it reported doing anything at all to video even when choosing uncompressed? There's a "deep analysis for better quality option" for instance, yet if I'm doing an uncompressed backup, wouldn't this be pointless?

BLAH - will just have to re-burn and see if it happens again. Sounds like the best solution. If someone could tell me reliably that they've backed up Dusk Till Dawn and NOT seen this issue (it is VERY noticeable in the Dimension logo), I'll feel a lot better.

@midimidi... no DVDShrink won't touch the video if you check uncompressed. The deep analysis is only for transcoding..that has nothing to do with a 1:1. Although...why would you use DVDSHRINK for a 1:1 copy? You can just use any ripper such as DVD DECRYPTER or Smart Ripper for example..and rip the files or rip in .ISO mode with DVD DECRYPTER....copy..simple as that.

You are using good quality disks...no reason to reburn the movie....take your disk to friends places, family...wherever..and see if their standalones show the same affects. It may very well be your standalone having some issues with burned media..and NOT having the issue with commercial disks. Did you try the disk in your DVD ROM? You seem more concerned with this logo thing...it almost sounds like you did compress the disk somehow...I know dimensions logo is surrounded by an entirely black background...i'd think any compression proggy would compress more at that point..because there is so much black in the background which is not actual video. Try to test other standalones first....as well as your DVD ROM...and then let us know how that works.
