| | Posted: | | | | Hi does anyone know how the disc ID is generated for example
<DiscIDSideA>1B007066313B350D</DiscIDSideA> is for Flight Of The Phoenix
When I read the disc in vbscript using serialnumber it returns 1959489750

| | Posted: | | | | Jolly, exactly how it is generated is probably best understood by Ken, it is somehow generated per some standard that I believe Microsoft has established, that said it definitely has nothing to do with what you are doing.

| | Posted: | | | | Unfortunately no. This where I started looking at the serialnumber. But I unable to make any relationship between the serialnamber and the discID.
Thanks for the reply |

| | Posted: | | | | From what I remember Ken did say it was based on a MS algorithm, and I also recall it being based on the disc content and not the serial number. The reason for this was because the serial numbers were far from unique. | | | | IVS Registered: January 2, 2002 |

| | Posted: | | | | Pretty much as Lithurge says, MS uses a calculation algorithm to produce a (statistically probable) 'unique' ID. I've been trying to find if this algorithm is in the public domain for my own purposes, but haven't been able to find anything yet. The algorithm is part of quartz.dll and the call is GetDiscID. If this info leads you to the algorithm, I'd be very interested to know about it. Stuart | | | This is a sig... ... ... yay...
Don't understand? Maybe DVDProfilerWiki.org does! |

| | Posted: | | | | Hi
The reason for trying to get ther disk id is
Have created vbscript which runs with sonyxlb1 changer
when the disc loads pauses to permit anydvd to operate then calls dvddecrypter. If dvd label is dvdvideo for example and this folder already exists then creates folder dvdvideo1 and so on.
If could find out how to extract discid then could use collection.xml to get the title and create a folder using title name |

| | Posted: | | | | I believe the routine is part of DirectX. I'd start looking in DirectShow maybe (which is code named Quartz). | | | Get the CSVExport and Database Query plug-ins here.
