got VCD (with some copy protection)

[fcml]

Hi all

I got a new VCD with some built in copy protection this is not a commerical copy protection. When i inverted it i can see thin circle bad/weak sectors also one other thing the MPGAVI directory was not accessiable via explorer, when i when via DOS i could go into the dir but no file viewing. They had a stand alone player for veiwing it on PC.

I wanted to know how i can create such a CD. Which will be the ideal method and software. By which i can add weak/bad sectors and disable the dir for acessess.

Also how do i get a raw image of a VCD. Which software is idea?

I know that Alcohol 120% has the 'Video CD' and 'Video CD with broken sectors' Disc Type(s), between the options. But I never saw one like yours....

From what I have read in other forums, commercial VCDs in India are often copy protected. I know the original post says it's not a commercial copy, I'm just pointing that out. A web search might lead to more info on this.
fcml - please note that any copy protection on VCD violates VCD standards and may make a disc that can't be played on some players.

Bet I could get to the track in 5 minutes with ISOBuster--even without a compliant Filesystem, the M2F2 track is still there...otherwise it wouldn't be playable in settops. Just like the axiom says!

Commercial VCD's in India are not really copy protected. Some of them have deliberately damaged sectors on the disc. They depend upon the fact that standalone player are more tolerant and skip the damaged sectors easily. While playing the film there is a temporary glitch and about 5/10 seconds of movie is lost. When you try to read such VCDs on PC CD-ROM, they get stuck at the bad sectors.

It is not possible to copy protect VCD's.

You can actually copy protect VCD's, but the problem is that the copy protection will not prevent experienced users from copying the VCD or from copying the dat file.

So what kind of copy protection are you talking about? Because I have not see any - other than what I mentioned before. I am also wondering whether it is possible to incorporate Macrovision in a VCD.

The copy protection I'm talking about is done by using a dummy track and by using a modified VCD structure.

It is possible to stop digital copying of VCD's. The iso data
after the leadin is blanked when making the mirror master.
You can see a blank ring at the center of the pressed VCD.

Computers cannot read the file allocation table and the vcd
is rejected. Standalone players, however, do not need to read
this section and so jump to the next readable part which is the
raw mpeg header.

You can also damage a VCD in parts (like a series of pinholes) to
prevent digital copying. My question is why waste your time?

BTW dummy tracks can be beaten by raw reading and writing
as afforded by software such as blindwrite.

What software can you use to make a vcd not readable in PCs? I heard of this one but I cannot really find any software or tools that can do this.
