VCD copy-protection Done!...DVD next

[kamuixtv]

Our small research group in the Philippines that created VCD copy-protection are now exploring the codes of DVD. A few people in the West commented that the protection is "useless", so we decided to put our efforts on creating a DVD-Video disc that can be played only on standalone players. The copy-protection is meant only for DVD burners, let Macrovision do something for expensive DVD recorders.

Copy protection ultimately is useless (though it may be very effective in preventing casual copying).

I maintain that there is absolutely no way of making a VCD "copy proof". This is ultimately as the sectors containing the video must still be ultimately readable by a stand-alone player that uses no more than a standard CD/DVD drive. You can probably fool the OS with some methods, but due to the above limitation, with the right software, you can always still extract the relevant sectors.

However, this isn't a debate about "VCD/DVD copy protection". Please don't use the Latest News board to advertise your product without prior consent.

I forgot to mention that it is not copyable by clonecd, clonyxxl, cloner or whatever software that exist...I can send you a sample. This is a service not a software anyway.

(1) It is impossible for you to verify that it is "not copyable" by every combination of software and hardware
(2) No advertising (services included).

BTW, you sent me an IM about getting a sample but you refuse to give out technical details. Well, sorry, but I'm not impressed. True copy protection (like encryption) is good by virtue of its technical design and is verified by public scrutiny. It is not by keeping it "secret".

As I have stated a number of times on the forums before, for a VCD to be recognised and playable as a VCD on a stand-alone player, there are a number of requirements:
(1) working TOC
(2) correct data written at the predetermined sectors for the PBC
(3) readable sectors at the MPEG tracks

I maintain that for those conditions to be true, it is impossible to make a VCD truly copy protected.

If your copy protection method is anything like those awful VCDs that can't be played back on the PC (i.e., broken or non-existent ISO filesystem), people have been able to copy these. Search the forum and you will find.

Regardless of the effectiveness of your "service", the forums are not a place for advertisments.
