1st) C2D will only write to my 2.4x media at 2.0x. This is despite trying to set the max speed to max or 2.4x . Any ideas - it's not the media - nero is quite happy to write at that speed.
2nd) change book type to dvd-rom when doing video. What is this supposed to acheive - when I write a disc i get a message saying it can't do this!
