Here is my problem. I'm using Clone DVD to copy movies to my hard drive. Then latter, I will go back and use Clone DVD again to write the movies to a DVD disk. 4 out of 6 times I tried last night, the program would lock up before it finished writing the movies to the disk. I tried slowing down the burning speed all the way to X1, but it still locked up. It is not them actual files on the hard drive, because I have sucessfully put it on a DVD before. Any ideas?? Thanks for your time.
