Not sure where to post this, because I am not sure which module is creating the issue. DVDFab is for backing up DVD/Blu Ray discs, so you can save the originals and beat up on the backups instead...However, since installing Bitdefender Internet Security 2013, I can rip the movie to the HDD, but if I want to shrink it down to burn back to a BD25, Bitdefender won't let the program get any more than 15% into the shrink, before DVDFab stops working. Have done this about a dozen times with the same result. Only solution was to uninstall Bitdefender...then DVDFab works fine. The makers of the program are aware of this issue, seems that many others are having the same problems, whether with Win 7 or Win 8. They are trying in the labs to figure out why, but cannot. So until then, I have BD on two machines and my third machine is back to my Kaspersky IS 2013 license until it runs out. I am hoping someone can shed some light...
Thanks
