i'm sorry in advance if this has been asked alot before.....but......
i am burning dvds on to my new fire wire external lacie drive from my Ibook... i am using toast 5.1.2.....
my problem is that it burns fine untill the finishing, when i get

sense key= illegal request
sense code=0x72, 0x03
session fixation error- incomplete track in session

it then finishes and says it succesfull....
it then can read ok in my lacie, but in by computer drive, it is a udf disk and it doesnt always read, saying it cant recognise a folder,sometimes its ok
i have tried to burn on slowest speed,
i have tried to turn off extensions
however i am using cheapish disks- intenso
