Your diagnosis was excellent, DVD-R worked OK. Retried new and used DVD-RW, with and without 'Erase rewritable discs if they are not blank' and both failed. Many thanks.

My DVD writer is a LG GSA-H22N which handles all DVD formats, Express Burn is version 4.05 and I am using DVD-RW discs.

I have just downloaded Express Burn and tried to use it for the first time (so I may be doing something stupid). I have selected a two photos and a folder containing a few more photos. When I press Burn DVD it says Already Burnt 0.06Mb and Total Used 5.84Mb and then fails saying 'the disk has a capacity of 0.6Mb and you are trying to write 5.9Mb, try fewer files or a larger disk. Why doesn't it recognise the disk as a 4.7GB disk - I have selected Data DVD?
