This seems all messed up to me
First here is the media info (problem is the same with all media types and discs though).
Ritek 4X DVD+R:

All scans is done with an LTC-48161H at 2X CLV.
Normal scan: 1ECC, Realtime chart ENABLED.
This one is also set to 1ECC but realtime chart is DISABLED.
This one is set to 8ECC, realime chart ENABLED or DISABLED do not make a hige difference here.
The only result that looks ok to me is the first one (1ECC with realtime chart enabled).
Also while scanning different discs at 1ECC with realtime chart enabled gives different results curves etc just like there should be but with realtime chart disabled or ECC set to anything else than 8 the amount of errors is about straight from the beginning to the end.
Any thoughts? Hopefully I’ll get a LDW-411S from Lite-On in 2-3 weeks or so for review…then I could test this behaviour on that drive as well.
For now it seems like I should only do my scans at 1ECC with realtime chart enabled.
