For a few days now, my 811s (HS0P) only produces unplayable DVDs. Im am always using 4x +R's by Verbatim (datalife plus) and never had any problems. Now, not only my Standalone won't play them anymore (about half way through the disc), also K-Probe (with165H) produces PIs up to 800 before it gives up with unrecoverable read errors. Before, I always got PI/PO averages at about 20/3.
I always was able to burn the Verbatims at 8x, but also reducing burn-speed to 4x does not solve the problem.
I reflashed HS0P - no changes.
What I SEE on the medias "data"-layer: dark-gray shadows, on some I see something like a dark-gray "hole" about 0.5 cm large close to the the outer border.
Do you think, that this problem is burner-related or due to a recent upgrade of my computer (MoBo ASUS P800P Deluxe, 1 GB RAM)? There is no sign, that data-transfer-speed is not big enough, so no burn-proof "events" are caused.
The 811s is only three months old, I have burned about 40 DVDs so far.
Any suggestions how to solve the problem?
Could it be HS0P (that produced good results so far)
Could it be the bitsetting to DVD-ROM?
