Hello.Maybe your burner's DMA is off.Right click on My Computer and Select Properties.Click the Hardware tab and then the Device Manager button.Click the "+" beside IDE ATA/ATAPI Controllers.Right click on both the Primary and Secondary IDE Channels (one at a time) and select Uninstall.Back in Device Manager, click the "+" beside the DVD/CD-ROM Drives.Right click on the name of the DVD Burner and select Uninstall.Restart the system.The above should reset the drives and controllers.Also make sure you have adequate hard drive space and that your disk is unfragmented.Edit: AddedIt could also be copy protection on the DVD you're attempting to backup. Are you using AnyDVD in the background? Are you ripping with DVD Shrink or are you processing an already ripped file(s)? 23 Jul 2006 @ 17:47
