DVD2SVCD - (interesting?) questions about the BIN-files created by DVD2SVCD

[Fsound]

Hi there,

these questions belong to the BIN-files created by DVD2SVCD

Allright, now here my questions:

- why is the BIN-File created by DVD2SVCD a two track CD? => I have got many SVCDs with ONE track only
- would it be possible (for the programmer) to remove the EXTRA directory? => I think there is no use for the file (dvd2svcd.xml) in this directory?!
- why is there a MPG-File in my SEGMENT directory?
- when I load the CUE/BIN-files with "IsoBuster", the filesystem is 2048 Bytes only ... I thought SVCDs are 2353 Bytes?

okay THANKS a lot :D

just two points:

1) those bin files are not created by DVD2SVCD. They are done by vcdimager;
2) it seems that you don´t have even a clue about the SVCD structure. My advice is: read vcdimager manual.

[Fsound]

yes, it's right - I don't have a clue about that ...
but I wouldn't use a frontend like DVD2SVCD if I should read 1000 manuals ...

Every SVCD I'm getting is 1 track only - not 2 !!
Every SVCD I'm getting doesn't have an EXTRA-Directory !!
Every SVCD I'm getting doesn't have a second MPG-File ...

And if I remove those files and tracks, it works everywhere ...

Can I cut out the copyprotection-tag in the CUE files?

The SVCD specification has 2 tracks. If you have discs that have only 1 track, then they are not SVCDs. They may have similar attributes and may work in SOME SVCD players that will play your non-compliant discs, but if there is only 1 track then it isn't an SVCD.

CUE files have no copyright flags or anything of that nature.

FLAGS DCP

DCP = Data Copy Protection

that is why some burning apps say "these is copy-protected material"

How Herbert Valerio Riedel writes vcdimager to function is beyond the scope of this forum. I would suggest you email him. He is a great guy and I am sure you will get a crystal clear reply from him. Look in the dvd2svcd\vcdimager directory for contact info.

Thought I'd put in my 2¢ worth on the original questions:

> - why is the BIN-File created by DVD2SVCD a two track CD? => I have
> got many SVCDs with ONE track only

I believe an SVCD has to have two tracks if you want playback control. A lot of us want PBC in order to get chapters. Your one track SVCDs may support chapters via entry points (or might not), but I know entry points on SVCDs generated by vcdimager don't work on my player.

This file is pretty small, and will be a god send to anyone if they ever need to re-burn an SVCD (the original is damaged, but is still readable in a CD-ROM drive, for example).

> - why is there a MPG-File in my SEGMENT directory?

Did you have the intro picture or change CD picture selected? I think you must have had.

The SVCDs created by vcdimager are mixed mode.

The first track holds all the PBC (and extra) stuff. This is a normal data track, in mode 1 or mode 2 form 1 format, which has full error correction and 2048 bytes of user data per sector.

The second and higher tracks holds the actual video data. These are in mode 2 form 2, which has very little error correction (not needed, because mpeg is fairly resistant to bit-errors) and (I believe) 2324 bytes of user data per sector.

To get to the kernel of your questions, I suspect you're concerned because this two-track structure is reducing the size available for your encodes. *But* the truth is the first track typically takes less than 4 MB of the CD (including the intra-track waste), which is less than 1% of the total space. No matter how good your eyes are, or how good your ears are, I very much doubt you'll ever notice the difference.

Thanks a lot ...

that was the answer, I as waiting for !!!

But still the question, why ISObuster shows only 2048 sectors on all my DVDs, even on the MPG-Files :-((

If they are REALLY 2353 or 2324 Byte my DVD won't rcead the CD for copying ... that is my main-problem.

[Mozart]

all of those informations provided by Kedirekin are in vcdimager manual. :rolleyes:

ISObuster is not so good to read BIN/CUE files (if you didn´t realize yet, BIN/CUE files are different of ISO files). If you want to see the structure of your bin/cue file, use CDmage instead of isobuster.

btw: about this sentence:
but I wouldn't use a frontend like DVD2SVCD if I should read 1000 manuals ...

that is true. However, if you are trying to understand how does each one program used by DVD2SVCD works, it is MANDATORY to read the documentation available.

[Fsound]

Okay, I am convinced finally. :D
CDmage has shown me 2353bytes
But CDmage cannot read Nero-Images of (S)Video-CDs :(

One question to the DVD2SVCD-Programmer:
I know, the XLM-File is such small, but could you create a switch in DVD2SVCD to tell VCDimage to leave the file out?
The reason is somethink like a small "security hole":

In this XLM-File you can see the directory and file, where the MPG etc. was located.

[SiliconSoul]

this program is for legally backing up your dvds
not you friends and the rental store and etc. if you are so afraid if this file then find a program that will let you change the bin/cue to extract this file out. or just use nero and burn the mpg

[Fsound]

hehe, it is for my DV-Records - not for DVDs.

but I want it perfect ...

mhm ... then I have to try the manual way.

Thanks

I believe authoring is the final step, and is relatively quick. DVD2SVCD leaves everything you need to complete (repeat) this step yourself. Just modify the XML file as you want, copy the vcdimager command line out of the dvd2svcd log file and paste it into command prompt window. I think this manual step is simple and quick enough that a request to change the program is not justified.
