I ripped Happy Feet using DVDFab. I then used Shrink to open it and rip it into an ISO. I deleted the ISO after burning it, then tried making another ISO with the same movie...and twice now, in the process of ripping it to ISO (from the HD folder) it restarts my computer. Anybody know what's going on? I tried several other movies after this happened and none of them did anything out of the ordinary while ripping to ISOs.
