I have just purchased an externa LiteOn +_ DVD writer. I installed it into a usb 2 port. My computer reconizes it. So does my Nero 6 software. I am running a 1400 Mhz with 1 gig of ram. Whwn I open DVD Shrink and click open disk, I select the "I" disk letter that shows the movie in the disk. I get this "DVD Shrink encountered an error and connot continue...Failed to read "I:\".... Incorrect function. I also tried open file icon. Went to the drive and found the Video_TS folder and I received the same message. If anyone can help me it would be most appreciated.
