I have two dvd drives, a Liteon SHW-1635S and a 16x8Dual MicroAdvantage DVD.
When i do a Nero scan on the same Verbatim 16x dvd on both of these drives, i get very different results. the liteon dvd gives over 5 PI failures, but the other drive gives no failures. The Microadvantage does not show PI failures or give a bottom graph. which reading do I accept as the most valid?
The second confusing thing is that i thought PI failures were bad, but when i scan the DVD using CD Check, the DVD comes up clean. Are PI failures synonmous with CRC values check in CD-check?
The third problem is that Nero speed disk gives very different results depending on the drive speed of the check. what drive speed should i use?
Hereto date i had been using CDCheck to verify that my DVD’s wouuld not hang and it was a reliable method as if i had no crc errors, my dvd would work fine. but now nero gives PI errors in the same dvd that cd check says is fine.
Can anyone help?
