I have a really weird situation here with my Liteon 812S@832S (currently CG3E). Whenever I update the firmware using omnipatcher (thanks codeguys!) I just apply the recommended tweaks and enable bit-setting and cross-flashing, nothing else.
The good.png image is a representation of what my usual burns are
Then, today I decided to burn 3 DVD+Rs, same media, same firmware, but a change in results (see bad.png for a representation).
As far as I can tell I haven’t changed anything, Nero version is same, firmware is the same, Ultra DMA 2 is enabled as has always been, I haven’t installed any new burning software…moreover media is the same (even same spindle!). I even monitored one of the bad burns and didn’t notice CPU usage to spike at any moment during the burn, and the buffer was always 100% (or very close to it).
Any ideas what’s wrong?
Or steps I can take to find out and return to the good burns?
For the bad burns, will they still be readable for DVD players (I can’t test that at the moment)? I realize they’re out of the acceptable range for PI/PIF errors.
The only thing I can see is that physically on the bottom side of the disc (where the data is burned), there is a small visible “ring” about 1 cm from the center that is slightly more visible on the bad burns than the good burns.
Thanks for your help.
