wow! once again, did as you suggested: opened roxio, selected tools, selected 'load disk image'
when you select this, you get a window called 'roxio disc image loader' under 'disk image list' is an 'add' button and a 'search' button. now when you select search, roxio does not ask for a file but looks for all iso files. however, when you select the add button you can then manually search for the file you want.
in the first case, Roxio did not find my file, which tells me Roxio did not see it as an openable iso file
when i added it, roxio would not open the file. which again tells me roxio does not see it as on openable iso file
i am assuming here that Roxio did not see it as an openable ISO file
ii do not have vlc, but what if vlc does not play the file? then we have two separate programs that say it is a bad file. if vlc does open the file, then roxio still will not make a usable dvd. i am still back to my question: how do i know if roxio is making a usable iso file?
