single layer copies don't work

[jimijames]

Hi all, I've tried to backup a couple of single layer DVDs, and all seems to go well, but my DVD player does not play them. I've made backups before without any problems, but single layer copies just don't work.

Can anyone help me with this?

Thanks.

What are you using to rip?

When I used to use Smartripper, many of the single layer discs would need the VTS sectors fixed with Ifoedit.

Make an image of the disc using one of your favorite software programs that supports images . Take that image and burn it onto disc . Should work fine since an image is identical to the original .

DVD-Decrypter works nice for this.

- ISO READ
- ISO WRITE

Two step, EASY, fast single layer burning solution.

Great for figuring out where any problems may lie.

Hope that helps

I use DVD-Decrypter to rip in file mode. What is the difference between that and ISO read mode?
I have a file which is already ripped with file mode and I have since lost the original disk. How can I burn it successfully?

thanks for all the replies...x

Do you have 'a' file or all the files? If you don't have all the files from the DVD then that would be the problem.

Have you tried to burn it to more than one disk? Maybe you just have a bad disk or a bad burn. Try burning again to an RW disk and see if it works.

"File mode" - extracts the contents of the disc, piece by piece (file by file). It takes all the logical "movie information" off the disc, if you will.

So then when you later burn these files, you essentially have to "re-make" the disc (don't be confused with re-author, which is something else entirely). How the disc is "re-made" is somewhat up to the whim of the writing program. (Ie. It can screw things up). Nero was a big culprit for this, in that depending on what settings and versions you would use, burning the "file" way would sometimes get you a disc that wasn't dvd-player friendly.

ISO mode makes a literal "copy" of the disc, byte by byte. So that when you burn it, you end up with something that is physically the same as the original disc.

When you write from file mode, you end up with something that is "logically the same" (ie. the same information), but it's not necessarily physically the same (ie. the information could be organized differently).

So the end result is that writing files is more involved and has more things that can go wrong. Where as ISO mode is simpler and thus there are fewer chances for something to go wrong.

DVDDecrypter ISO Read --> ISO Write, is a good way of testing to make sure your Drive/Burner is working correctly.

Hi BobK, thanks for your reply. I should have said folder not file. The folder was ripped in exactly the same way I rip all my disks. They all work ok except the single layer ones.

Thanks aggies11 for your help and valuable information. In future I'll use ISO mode for single layer disks.

I'm still curious why ripping with file mode works fine with dual layered disks and not single layered ones. Can anyone tell me why that might be?

[aggies11]

re jimi:

Does the rip itself fail (in dvd decrypter)?

Or is it just the burning that has a problem.

If it's just the burning, what program(s) are you using to burn the discs?
(DVD decrypter only burns ISO's)

You can/could try using Nero (DVD movie) or CloneDVD(Write existing data) to burn the files that you ripped.

I use Nero to burn. The rip and the burn are no problem, its just that the single layer disks don't play in the DVD player, but the other disks, made in exactly the same way, work fine.

[aggies11]

Hmm, might be a software problem with Nero.

I remember hearing lotsa problems / issues with using it to burn DVD's.

Personally, I use CloneDVD for writing "files". (I figure cloneDVD is pretty specialized where nero does lotsa other stuff than dvd burning. So it has a better shot at working.


So give CloneDVD a shot (just for burning. Any version will do). That will tell you if it's a problem with nero, or a problem with the drive.

What program are you using to do the 2 -> 1 disc compression?

[jimijames]

aggies the thing is, only single layer disks don't work, even when I produce them in exactly the same as I do dual layer disks. I've used Nero to burn loads of disks no problem, and even the single layer disks seem to burn ok, its just that they don't play.

[aggies11]

Re Jimi:

Yeah that is weird. Which leads me to believe it's a software problem.

Ie. For dual-layer discs, you have to use some sort of shrink program, which produces a new set of files.

Where as with single layer discs, the files are the originals off the dvd.

I only recommend trying another burning application for testing purposes. If it works, then the problem is with nero. If it doesn't work, then the problem is somewhere else

But there is a difference between double layer discs that have been transcoded, and standard single layer discs. So it's possible that this causes a problem somehow.

Try decrypter ISO read/write, and maybe also another burning program
(cloneDVD seems to have a nice burning engine). The results from those tests should give you enough information to hopefully be helpful

The simple test is to create an image of your VIDEO_TS (and its content)and AUDIO_TS using imgtools classic. Then burn this image with DVDDecrypter. AFAIK, this creates a very compliant Video DVD that should play if ripped correctly.

hey jimijames.

This might sounds kinda wierd but i also have problems with my standalones playing single layer backups that are under a sertain disc size.

I dont know the specific size but i have made a 3 single layer backups that where 3.0gb, 3.2gb, and 3.7gb and they didnt work at all in my DVD players.

I ended up added some "dummy" filler files into the main directory of the dics to around 4.2gb. After that they worked, well in one of my dvd players anyways.

Its just a suggestion.... try it out on a +RW / =RW first/

I have since lost the original disk

What, it disappeared down Blockbuster's return chute ?
