Yesterday, I just made an image file (ISO) of an original DVD-9 movie using Ultra ISO. Just now, when I try to play the DVD image (Mounting the image file via Virtual Daemon Manager) the DVD playback was jerky even at the Intro and Menu of the DVD and there are screeching sounds throughout the entire playback... Making the image file unusable! The screechings and jerkings occur at the same timeline during every playback which suggests that there is something wrong with the image file...
I've tried to make an image file for 2 original movie DVDs and both of them turn out the same... Help, please...
