ADIP, Boarder zone index/DVD sector?

Hello,

I’m currently writting a program for uni and part of it needs to access certain info on DVD and Blu-ray discs. I’ve done a lot of googling and asked compainies which sell dvd discs and related prducts + people who license discs but they won’t help unless I buy expensive licences ($4000).:eek:

Does anyone have or have pointers to infomation on which sectors contain:

I think the bellow hold info about the recordable discs themselves which is used by write drives when burning on discs. This is stuff like disc manufacturer, compatible writting speeds, date + time etc:
Address In pregroove ADIP on DVD+R discs
Land pre pit on DVD-R discs
Something like this on blu-ray

Also the boarder zone index. I’ve found stuff from the primary volume descriptor which I think is on sector 262 on dvd’s. I’ve been doing unicode and ascii keyword searches using a program called winhex and can’t find what I’m looking for.

Thanks for any replys.
