1 - Kprobe is Not applicable to other burners than Liteon. U can burn disks with every burner , but the DVD scans Must be performed with Liteon's.
2 - Nero DVD quality does not support Samsung
3 - The last choice is DVD infopro, that is out today with a new release
I made a try with both kprobe and DVD info pro at max speed. The error profile is quite the same, but the Average value is less with Kprobe.
Anybody with a Liteon - Samsung combo can post a comparison ?
