| Post subject: | Manufacturer Disc rot? |
I just saw the top 10 list of all manufacturers whom suffers from discrot. http://www.lddb.com/laserrot.php I was shocked that Pioneer USA and japanese division comes on 2nd and 3rd place as the worst companies? I thought Pioneer was one of the best disc manufactorers? i hope that not all discs reliesed by these top 10 companies are affected by the dreaded cancer? |

They aren't necessarily bad, it's just that they manufactured so many discs. Also, laser rot is relatively rare imo unless you're looking for it or buy Disco vision titles. |

discovision discs are they known to be bad? i always ask the seller before i buy the disc, if there are any signs of rot? some discs does have stains of visual rot, others don't show any stains but still might have been affected by rot? it feels like i'm buying the pig in the bag everytime I buy a laserdisc. i can only trust what the seller tells me, disc has no visual rot when it still might have it because seller didn't inspect the disc properly? buying used discs is tricky business as a buyer. |

I noticed a big rise in rot when I switched from buying music titles to movies. Far more movies than music titles were pressed by Sony DADC in the USA and it sticks out like a sore thumb how bad those pressings can be. Of course if you buy enough music you also get to know the rotters there - these are main Japanese ones to be wary of:
Pack In Video - almost always risky!! You may need to buy 10 copies of one disc to get a nearly perfect copy! Pony Canyon - generally older 80's pressings were very good and the early 90's pressings were the ones to avoid. |

Laserdisc was the first commercial optical disc format and Discovision discs were the first launched Laserdiscs on the market. In other words, Discovision discs are truly pioneers but also suffering from numerous of playback issues and rotted discs. I only have one Discovision title in my collection, Jaws, and I only own it because it was the first Laserdisc ever made. Buying a sealed disc doesn't guarantee getting a rot-free. It's a blind buy but unless the title is known for being a rotter, you shouldn't worry. |

i have now checked the laser rot status on all my discs on lldb database only possible candidate for future rot or already might have is Passenger 57? i have bought this disc factory sealed, seal is still intact. Passenger 57 (1992) [12569] next question: discs that had no previously reports about disc rot seen in the database (NONE REPORTED), are these still possible to be contaminated by rot in the future? |

The ranking of manufacturers for rot is calculated in a way that is not normalised for the number of discs from each manufacturer in collections, so it doesn't work as a predictor for rot likelihood from a manufacturer. I have posted about this at least twice with no response. FWIW, my experience is that PDO UK is by far the worst manufacturer, with well over 90% of their discs in my collection rotted to some extent. |

Hi PDO = Philips DuPont Optical. But the UK-published Universal Soldier was made by Pioneer Japan and AWOL too. |

Bear in mind that UK editions are sped up 4% due to the films running 25fps instead of the 24fps for the NTSC variants. And I really don't want to get into another LaserRot and DiscoVision argument here. No one will dispute that DiscoVision did have quality problems and their discs are subject to a lot of speckling and helicopter audio (on CLV titles). But in terms of "this disc used to be fine and now it's garbage", this really doesn't happen on DiscoVision titles. If you find (or have) a good copy, it should always remain good. DiscoVision discs - even the newest one - are over 30 years old and I expect any deterioration that is going to happen has already done so. |

I believe that NTSC editions are 30fps? to meet 60Hz.... PAL is 25fps (x2=) 50Hz |

PAL is 25fps (x2=) 50Hz Yes, that is true - they are actually running at 30fps, but for film playback, NTSC incorporates a 3:2 pull-down where some fields are duplicated to fill out the extra 6fps. The point being is that PAL playback speeds up the program, where NTSC does not. |

Well, buy 100 Philips discs (PDO-UK) from around 1990 - 1994 and you will have 100 rotters  (Some cases so bad, they won't even play)
