Code:
Lentgh Code: 00 22 00 00
Volume ID: 40 00 04 06 32 04 20 11 57 47 48 44 56 4D 00 00
MAC: xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx
Thats a Volume ID indeed. And the unique 12 bytes are much more random in this case (although the last six sort of look like ascii characters: assuming you got this from WinHex: how does it show up in the Ascii part of WinHex?). What movie/distributer is this from?
I still see structure. Maybe we can figure out what it stands for (like the date/time thing in my example).

PS. Its best to remove the MAC bytes like I just did for your own protection.
