I suppose sometimes DADC Austria would use as a 2nd source for NTSC titles. One good example is Philadelphia (1993) [52616] carrying LDVS-002160/LDVS002160 for both masters. Julien

admin wrote: Relaxed some conditions for partial mint marks and the total jumped from 3,304 to 5,096. Made another round of improvements to cope with variations in the Pioneer USA mint markings. And while I was having fun coding array parsing, I added BOLD for continuous master serials and BOLD RED when I detect the longest continuous sequence. https://www.lddb.com/mint/pioneer-usaAs of today: Total = 5891 The longest continuous sequence is 21 starting from 58-330.Improved again: Total = 6382The longest continuous sequence is 28 starting from 59-243. Made the same modifications to SONY DADC: https://www.lddb.com/mint/dadc-usaTotal = 1246The longest continuous sequence is 10 starting from 001198. Help us fill the gaps Julien

Julien Pioneer USA never went above Side "F". Titles which required more than 6 sides would have the internal reference number advance. For example, "Gone with the Wind (CAV)" is: 51-989A1-07 51-989B1-01 51-989C1-06 51-989D1-05 51-989E1-01 51-989F1-02 51-990A1-04 51-990B1-01 51-990C1-02

We could maybe extend the same reverse engineering to PRINCO: Few examples: KA7984P/KB7984P A36955D/B36955D A368657/B368658 A2637-0Q A305848/B3058B5 A292836/B292836 A31286P/B31286Q KA4067F/KB406HG A29864F/B29864F KA22132/KB22131
Except for KB406HG (typo in Amelia, Volume 1 (1993) [AMI-001]?), it looks like was have a master serial ID embedded: KA 22132 A 2637-0Q A 36955D A 29864F KA 7984P A 379888 KA 1661Q KA 1040NO A 38098P A 2723-NF A 3967BP A 2704-NL KA 0079-D6 A 292936 Would that make sense? Julien

Although it does not look like Pioneer USA were using hexadecimal logic, perhaps they were limited to the hexadecimal character set in order to comply with some internal database.

To help locate titles that still lack the Mint Markings information, I slightly modified the Collection list colors for LDs (that are not graded 9 or 10 -- don't want you to open a sealed disc just to check the mint marks!): => https://www.lddb.com/collection.php?action=list&format=ldIf you see some red-ish lines... there's some updates needed Julien

If not already so, would it be worth a try to match DADC USA just on "LDVS"? I noticed that the early mint marks might be quite different. Attached is a photo of Warrant: Dirty Rotten Filthy Stinking Rich: Live (1990) [ID6971CB]DADC USA replication began in March 1990 and the oldest DADC USA mint mark currently in the list is Kickboxer (1989) [ID7320HB] which lines up quite nicely with its September 1989 theatrical release.

Not sure why DADC USA had 2 different master naming schemes... Slightly modified the parsing and now we have a few more! Now the trick is to NOT match DADC Austria for multiple sources of the same title. I'm padding the different ones with 0 to merge with DADC Austria when a title was manufactured at both sites. Julien

admin wrote: Slightly modified the parsing and now we have a few more! Excellent! admin wrote: Not sure why DADC USA had 2 different master naming schemes... Yes this is puzzling to me as well. I noticed how Technidisc changed theirs in a much more subtle manner three or so times. Right after the Terre Haute plant started LD replication, they declared they were scaling up from 100k to 300k monthly within a year (source: a Telecommunications Update article from 1990). My guess is they underestimated demand and then threw a massive amount of money at the factory, casually scrapping the new "old" equipment. Warrant: Dirty Rotten Filthy Stinking Rich: Live (1990) [ID6971CB] has sharp edges that are uncharacteristic of all the other DADC USA discs I've handled. Even though it does show LDVS034 in the mint marks, LDVS 000034 is on the label.

cplusplus wrote: Is the additional identifier LMDD1234 or DDML1234? There is a clear pattern that could look like YMDDNNNN indeed, but it's not the only one. Took all the mint marks associated with Pioneer USA that are in the form of 5x-xxxxx-xx(x) zzzzzzzz where the z's are the 8 stamped characters. That's 2,943 sides but... oh my, so many typos that I deleted the ones submitted obviously after too many vodka shots and trimmed down to 2,930. Then we have several schools of thoughts (L = Letter, N = Number): 2,468 as LNNNNNN where L is A to I 428 as NNNLNNN where L is A to D and the matrix runtime is 5x-NNN[AB]NN- NNN instead of 5x-NNN[AB]NN- NN ex: R.E.M.: Road Movie (1996) [ID4165WO]18 as NNLNNNN where L is (A,C,F,G,H) ex: Jailhouse Rock (1957) [ML102564]12 is NNNNNNNN but they all start with number 1, I suppose it's meant to be the letter I ex: Cows (Vacas) (1992) [SKL-1004]3 as NLNNNNN, ex: Pin Ups: A Picture History of America's Dream Girls (1994) [LVD9532]So, if we focus on LNNNNNN, it goes like this: A1 to A3 (no example of A0) B0 to B9 C0 to C2 (only 4 in C8 or C9) D0 to D9 E0 to E9 F1 to F2 (only 2 in F8 or F9) G0 to G9 H0 to H2 I0 to I9 0-9 is 10, not enough for 12 months but here are also 0-2 providing an additional 3. 13 months? Next digit is likely a day, because it mostly stays within 01 and 31. Have examples of 31 for: B0, B1, B5, B7, B8 D0, D1, D5 E0, E7, E8 G0, G5, G7, G8 I0, I1, I3, I7, I8 The only 2 consecutive months with 31 days are Dec-Jan and Jul-Aug. Here we have examples of 0-1 and 7-8. So we could think that: December = 0 January = 1 July = 7 August = 8 If 2 is February, is Feb 29th common? No I only have 4: C2Duran Duran: Extraordinary World (1994) [PA-94-541]Tom Petty: & The Heartbreakers: Playback (1995) [PA-96-569]F2Coeur en hiver, un (A Heart in Winter) (1992) [LV24339]Trisha Yearwood: The Song Remembers When (1993) [PA-93-539]3 release in 1994 (not a year with Feb 29) and 1996 (that one works). Still no general rule... And Japanese companies are too bent on applying rules, we must be missing something. The feeling is LN is a date encoded (year+month) or a date from the first use of the master with a backing database? Or a twist because Japanese engineers would start counting from April (new year in Japan) instead of January? Now looking at the next category NNNLNNNN, it breaks down to DDMLNNNN. Days are quite obvious but the month on 10 values (0-9) and the Letter only A-D is still puzzling. Julien

Excellent, thank you for accumulating all that. Very intuitive to check for leap day. I would really like to double check those discs, even though I would bet they are correct. For more insight I checked some Pioneer discs I have near (D is DB, M is mine): Drop Zone (1994) [LV 32734-WS]D: 54-536A1-14 I7080578 M: 54-536A1-04 I5234210 Stargate (1994) [LD 60190]D: 54-326-A22-P I1178665 M: 54-326-A18-P I1086791 Goldeneye: Special Edition (1995) [ML105544]D: 59-212A2-55 B5150214 M: 59-212A1-28 B4190017 Body of Evidence (1993) (Uncut) [ML102987]D: 58-413A1-07 E5180859 M: 58-413A1-04 E5161719 Letter changes: Cool World (1992) [LV 32356-WS]D: 53-123A1-17 E3010336 M: 53-123A1-29 F1150593 Clear and Present Danger (1994) [LV 32463-2WS]D: LV32463-2WS-A07-P I4121761 M: LV32463-2WS-A06-P H2147942 In regards to my previous comment on 'L' being stamper related, I believe that information is in the other number: A1-04 might be Side A Mother 1, Stamper 4. It looks like as the mother/stamper numbers increase the date codes do as well. This is very tedious for me to check, but I'll continue to try to find an explicit contraindication.
