I've searched and looked through the forums, perhaps in the wrong place, but i can't find info on how to interpret my scan results. The drive is a 1673S with JS05. DVDs are DVD-R 16x Verbatim (MCC). Here are two sets of results.
The first burn (first 3 images) is of a copy of a badly scratched disc originally made by a settop DVD Recorder (my brothers). The original image fits on a DVD5 disc without compression. The Max burn speed in DVDDecrypter was left at "MAX" and as mentioned, I used DVDD to rip and burn the image.
The second burn (last 2 images) is of a clean disc of my daughter's. I wanted to make a backup so she wouldn't destroy the original when she plays it. It's a DL image. I ripped with DVDD and burned with Roxio (Roxio managed the compression). I limited the burn speed to 8x on this burn.
Thanks for the help and pointers on how to read this, and if it's bad, how to improve it.
