Sorry guys, just found out what was wrong, have to change from start multisession to no multisession, then xbox compatibility mode is there in udf section, cheers I just had to format my hd and then upgraded nero when i reloaded all my old software, in old nero when i wanted to backup my games i would ftp the files and then burn in nero using dvd(iso/udf) and the forced video compatibility checked and never had a problem. It seems this check box has been removed from the latest version from the udf page when setting up the burn and there is merely an option for automatice or manual partition settings. I know I could build an iso with craxtion, but I liked being able to cut out the middle man and never had any particular problems with most backups, anybody know if you can no longer backup this way or if there is a way round it????? PS sorry if this has been asked before but i did search the forum for a bit, thanks again
