I want to burn several copies of a DVD video disc & retain a ready to use file for future copies-when I successfully burn a disc & create an ISO image I am immediately denied access to my dvd recorder (by pic to exe) & have to opt for a 'lesser; recorder for the 2nd burn & I still haven't a clue what to do with this iso image -I've researched it to a certain extent but it's the usual problem -I've found out that it;s " an archive file (also known as a disc image) of an optical disc in a format defined by the International Organization for Standardization " but I still need the guy in the pub to actually TELL me what it is & what I do with it & is it what I'm looking for- it's a bit like the bottom of this page-I now want to post this but the button at the bottom asks if I want to 'post new topic' & therefore I don't know if ,when I press it ,I'll be directed to a new topic & have to start all over again or is it referring to the' posting' of the topic which I have already created- muddy waters
