issue with old burner were I/O errors with sector problems, these were solved with the new burner. The issue isn't about the burningspeed anymore, there where I thought that a burning speed of 2.4 was mandatory for brning xbox360 games. The issue is about closing disc/finalizing which isn't working with dl discs.
The firmware of Burner, motherboard etc is up to date, the burner does burn SL (eventhough the speed in the topic is to high). I'm still looking to burn DL on my PC.
Tried again, no result:
