From what I can see under google search, this is a common issue when copying certain HW DVD's. Unfortunately I'm still none the wiser on how to fix the problem. Here is the problem: 1) Loading DVD and decrypting files using DVD backup. 2) Files are copied onto my hard drive using same file names 3) As the file is to big for TDK DVD-R disc, I am basically going in and splitting the file before dragging the first part of the file over to Toast 6 and burning. This has been successful on two DVD's however the error (result code 18774) has come up while trying to burn two others. I have tried different burning speeds, still no good. One of the comments I read on google mentioned to use DVD2one?? I don't really want to purchase this if its not 100% guarantee although the thought of only using one disc to hold a movie is appealing. Is this a recommended purchase? Are TDK DVD discs no good? As I am fairly new to computers can anyone help me with the above? Thanks in advance.
