I thought the Verance Watermark Secure Digital Music Initiative (SDMI) had
already been been hacked (link)?, Jon Lech Johansen (aka 'DVD-Jon', the guy who officialy cracked CSS) released a
new SDMI crack (link) recently but his link is now dead
...however (as always), google to the rescue =>
Jon+Lech+SDMI search (link), and
SDMI crack DVD-A search (link)
