Why is it i have a disc which has a good CD-Speed scan and score of 94 is unreadable? See the screenshots below, i just don’t get it
Is this a pressed video DVD or a burned one?
If it’s a pressed probably the test fail because of an arccos copy protection. Anyway it’s only an hypothesis.
I would say that it is a pressed disc. The jitter is low and semi smooth but the PIF is horrid.
I agree that the error is probably due to copy protection on the disc but it could just be a bad spot, but unlikely
Well, it happens to me - recordable or pressed… a good PI/PIF score doesn’t always relate to a disc’s readability.
Had discs with better scores become unreadable … maybe BETA problems or TA problems or other pit geometry issues or even reflectivity which are some things this drive can’t measure. Find that scanning on a Liteon seems to make scans look worse for some unreadable discs, but I have even had false (readable) diagnosis from PI/PIF scans before… - scanning for PI/PIF is not the entire story!
This is the reason because other than scan should be posted also transfer rate test. Is the combination of these two tests that give most informations about a burning.
Well thats annoying. It is a pressed disc and its not a data encryption issue. Got a different eror messgae if anyone knows what it means.
Can anyone think of a work round so i can get the data off and blank out the duff section so i just get a few secs of a black screen or something as the disc seems to be mostly fine?
This error is typical of two main causes:
a heavily scretched disc
one of the new copy protections (mainly arccos)
Very likely to be one of the new copy protections if I had to guess.
