burn vob into cdr

[pcb]

i got a cd that contain vob, i assume it was minidvd , but the vob was 845 MB , how can it burn into cdr ? that the cd was only 700 MB ?

[aedipuss]

you sure it isn't svcd? cds burned mode 2/form 2 have less error correction data so they can hold more, but it's mainly only used for svcd. a minidvd should have been burned as a data mode1 cd with about 700mb.

i am sure because it has :
video_ts.bup
video_ts.ifo
video_ts.vob
vts_01_0.bup
vts_01_0.vob
vts_01.vob

If you go to your command prompt,
type "cdrecord dev=1,0,0 -minfo", and the damn application says
the capacity of the disk is 702.8 MB, then you can be sure your
cDVD is a regular 700MB disk. Still, it could not contain more than
800 MB of data recorded in Mode2/Form2, and would not be played back
by any "normal" DVD-player.

I wonder if this could be a 90 or 99 minute CD-R. They show up to burning programs as 700 MB CD-Rs, but the actual capacity is higher.

CD-Rs are required to have a small area I think called "lead in" that can technically be written to but is not normally used. This area is only required to be big enough to hold about 1.5 minutes of music, but it could be bigger. If this is really and truly a 700 MB CD-R, I would guess that Mode2/Fomr2 was used and the lead in area was bigger than normal and also used.

The only other possibility I have is that some Plextor burners were made with the ability to write more data to disc than the disc should have been able to store. This was due to partially writing to pits, but this feature never really took off and reviews I read about said that it was unclear if most devices could correctly read such discs or not. It involved a lot of Plextor proprietary stuff, but it could do things like maybe write the data for 4 bits in an area the size of 3 bits and so on. If this was used, it could squeeze more space out of a 700 MB CD-R, but this technology deviates heavily from industry standards and such discs can't be guaranteed to be played.

Finally, I've read about some weird things being done with DVD video where headers are deliberately corrupted to prevent copying. ARCCOS does stuff like this. Is there any chance that the data is actually smaller, but a header was deliberately corrupted and given an impossible size just to make the disc very difficult to copy? A normal copy program would certainly refuse to copy such a disc because a 700 MB CD-R would appear too small, so I wonder if maybe this is just some kind of copy protection in use.

i have tried to open the vob that contains 845MB, and whole of it contain a movie, i tried to direct copy ( not using any other program ) and it succed , it didn't show any of protections

Damn man....will this false, wrong, horse shit rumor EVER die?
Oversized CD media show up with ALL available space to utilize with the correct
burners and the correct burning software.

Space available....799.74MB - and no need to overburn because
you have 799.74 to use.

hech54 - I said what I said because the tools I have do indeed report such discs as being 700 MB in size. If you have something else that doesn't do this, perhaps you would be kind enough to name it. I have no idea what the heck you are using to burn from your post. I suppose the emphasis is on "correct burning software", so what do YOU use that correctly reports this?

The picture says ONES (Prassi Ones) and shows an LG-4167B burner. What else do you need to know?
A picture is worth a thousand words.
