Hi,Fran
I had no luck at the one to one session as their macs couldn't read the disc as well,they said perhaps the burnt disc needed formatting. Since I just used the standard windows xp program to do it I'd imagine that it would have been formatted.
So after that session I tried again to burn photos from pc to a DVD-r disc but this time I used my daughters windows 7 laptop, it gave me the option to burn as "USB format to be read by any pc running xp and above" or as a "cd/DVD that cannot be re-recorded" this is the one I used, hey pesto it worked.
So all I have to do is load all my photos on to a 7 machine and then take them to disc and import to my mac. No its far easier to put them onto a usb memory stick and import the photos you want that way.
Haven't solved the xp issues but sort of got it sorted there abouts thank you all out there in the community.
Cheers Lee
