Hello folks.
ImgBurn Read mode seems to be creating files on hard disk that are larger, sometimes much larger, than they need to be.
I use a Philips model DVDR3455H DVR to capture video, mostly short news reports, but sometimes whole shows. I burn the clips as titles, up to 49 at a time (the max for this DVR) to DVD+RW discs, and use ImgBurn to archive the discs as ISO image files to hard disk.
A while ago I became suspicious that the ISO files were larger than then they needed to be. As a test I used the DVR to burn a blank DVD+RW with a single half-hour show, which had been recorded at half quality, so it was equivalent to 15 minutes worth of a 2 hour DVD. The visible burn area of the DVD appeared right, less than 1/4 inch of disc radius, but when I read it with ImgBurn the resulting ISO file was 4,160,992KB. That's close to the entire disc.
The ISO files produced seem functional, but I'm wasting a lot of hard drive space storing the oversize files.
I don't know whether this is a DVR problem or an ImgBurn problem.
Has anybody else seen this problem?
Is there an ImgBurn setting that will force it to make the image size the actual size of only the burned part of the disc?
Or is this a bug that can be fixed?
I have appended below the log file and the disc information pane text from the test Read.
Thanks for your help.
