Hello. I have a PowerMac G4 and PowerBook G4 (Panther) and a Sony DRX 800UL DVD burner, with dual layer burning capacity connected by firewire to either machine. The Sony is recognised by, and works well with Toast, for regular single layer burning although it is not supported by Sony for Macs. Oh yes, I also have Patchburn installed, regardless. So the short question is, has anybody met any problems with dual layer burning? I understand that the quality of the media is a critical factor and I have held off as a result. Further, does Toast automatically recognise that there is a dual layer disc in the recorder and will it handle everything on its own? I cannot see any indicator for manual settings. Any experiences and advice would be welcome and appreciated. Thanks.
