I'm looking at a DVD which has been created by a user. In the root folder/text view in encase I see some details such as software used to produce dvd, software version, plus some generated numbers.
Simple question, these numbers generated, do they have any association with the system which produced the DVD's?

Based on the information you've provided, there's really no way to tell.
What was the software used to produce the DVD? The software version? What were the 'generated numbers' you saw?
If you're not willing/able to share that information, I'd suggest that perhaps the best avenue is to contact the vendor.
Also, can you clarify how this is a "custom DVD"?
RMD is last border. This often gives the model and serial number of the DVD drive used to write the disk
Well I have learned something as a result of this initial post.
Have a look at -

Ecma Technical Committee TC31 was established in 1984 for the standardization of Optical Disks and Optical Disk Cartridges (ODC). Since its establishment, the Committee has made major contributions to ISO/IEC JTC1/SC23 toward the development of International Standards for optical disks. Numerous standards have been developed by TC31 and published by Ecma, almost all of which have also been adopted by ISO/IEC under the fast-track procedure as International Standards. The following Ecma Standards for DVD 80 mm and 120 mm have been published by Ecma and adopted by ISO/IEC JTC1.
ECMA-267 (1997) ISO/IEC 16448
120 mm DVD-Read-Only Disk
ECMA-268 (1997) ISO/IEC 16449
80 mm DVD-Read-Only Disk
ECMA-272 (1998) ISO/IEC 16824
120 mm DVD Rewritable Disk (DVD-RAM)
ECMA-273 (1998) ISO/IEC 16825
Case for 120 mm DVD-RAM Disks
ECMA-279 (1998) ISO/IEC 20563
80mm (1,23 Gbytes per side) and 120 mm (3,95 Gbytes per side) DVD-Recordable Disk (DVD-R)
ECMA-330 (2002) ISO/IEC 17592
120 mm (4,7 Gbytes per side) and 80 mm (1,46 Gbytes per side) DVD Rewritable Disk (DVD-RAM)
ECMA-331 (2004) ISO/IEC 17594
Case for 120 mm and 80 mm DVD-RAM Disks

80mm (1,46 Gbytes per side) and 120 mm (4,70 Gbytes per side) DVD Re-recordable Disk (DVD-RW)
The documents describe in considerable detail all you would ever need to know about the structure of DVDs, including the RMD - Recording Management Data, for those amongst you like me who did not know what this meant.

Take care, in my experience, not all drives will read the RMD data. If one fails, try a different make
Appreciate the replies…just to confirm..the RMD found on a DVD corresponds to the DVD Player model number which was used to create that DVD?
My tests on about 10 DVDs all showed the correct DVD model and serial number.
I have not tested what happens when a new session is added to a DVD.
