Copy Protection

Perhaps the most amazing thing about some DVDs is that they play at all, given the trouble that DVD makers go to copy protect them. This is what AnyDVD HD has to say about the Toy Story DVD (which comes with the Blu-ray):

Video DVD (or CD) label: TOYSTORY1
Media is CSS protected!
Media is locked to region(s): 2 4 5!
Video Standard: PAL

Found & removed structural copy protection!
Found & removed invalid cell pieces!
Found & removed bogus title set(s)!
Found & removed invalid VOBUs!
RCE protection not found.
UDF filesystem patched!
Autorun not found on Video DVD.
Found & removed 15 potential bad sector protections!

Intentionally corrupted file systems and titles. Lovely.

    I’m a little surprised they haven’t gotten around to doing anything like this for Blu-ray titles yet. Piracy seems to be a big enough concern for studios like Fox to drive continual revisions of BD+ copy protection, but off the top of my head I can think of at least a couple simple yet nasty authoring tricks that would put a monkey wrench into all the current piracy toolchains (and probably a good number of innocent HTPC toolchains too unfortunately), but would leave commercial playback from original disc intact.

    Maybe I should patent these thoughts, so I can sue if they are implemented! 😉

    Perhaps AnyDVD is crying wolf? I once had a virus checker that included cookies and most-recently-used file lists as malware.

    Victor: No, I don’t think so. I normally try to grab DVD frames using VideoReDo Plus because of its fine controllability, and in most recent Disney titles that I’ve tried to use it with, the first *.vob file has been so badly corrupted as to crash it, even though it works fine with every other brand of disc.

    Chris: it probably largely depends on how carefully the PS3 checks disc integrity (since I gather this is the default test platform). Or, possible, the Blu-ray organisation has outlawed disc corruption protections, believing that BD+ protections will be sufficient (of course, nothing is sufficient).
