We just purchased TrueImage 8.0 and we were wondering why we can back up to the hard disk, and to a CD, but not to a DVD? It keeps saying that the media 'might' be bad, but we've tried every brand of media there is, and it never works (same media works with all other programs). I could post a screen shot of the error message if you need to see it. What else could be causing this? Thanks.
