none of my recent burns has scored particularly well in my quality scans.
The scans had all been done with the LiteOn DH20A4P, the burns with that same drive or with a Pioneer DVR-115D. The DVD-Rs were in most cases MCC004 (that had been delivered directly by Verbatim) and some Sony discs.
While most were still acceptable, the following scans indicate serious problems.
The first two pictures are from the same DVD, a MCC004 burnt with the LiteOn. Note the signifcantly better result at 2x testing speed compared to 4x.
The next two show scans from another MCC004, burnt in the Pioneer at 12x. Here the testing speed apparently made no important difference.
Are these problems most likely due to:
- bad quality media
- reading problems of the LiteOn
-writing problems of both the LiteOn and the Pioneer?
(or something else?)
Your thoughts will be appreciated.
