Has anyone seen a quality difference between discs burned directly from DVDA and copies of copies?
Reason for the question is......should I save the Video and Audio files so that I may burn directly from DVDA or just keep a copy as a master to make duplicates from?
There will be NO quality differences as this is a straight bit-for-bit copy of the original digital data. Just keep a master copy of the DVD and you can copy the Video_TS and Audio_TS folders back to the computer anytime you want to make additional copies.
Have you actually tried this? I did, and my computer refused to copy them back to the hard drive. When I checked the properties of the .vob files (right click/Properties) , I found they had been written to the DVD as "Read Only." Is there any way to set DVDA NOT to write as "read only?" I've checked the Options menu, but haven't found a place to set it.
Yes, I have done this when additional copies needed to be made of DVDs I had already removed from the hard drive. And, yes, they will be set to read only (as will all DVD-R and CD-R files when copied back to the hard drive). It works just fine.
When I try to copy VTS_02_1.VOB from the written DVD to the hard drive, I get the following error message . . . "Cannot copy VTS_02_1:An attempt was made to load a program with an incorrect format."
Any ideas on why I would get this message? Some VOB files will copy, but it seems that the large files that are a full 1,048,576 KB are the ones I can't copy.
The "read only" issue has nothing to do with it. I can see that now, because as you said they are all flagged "read only." Any ideas would be appreciated, because there are times I know I will need to be able to copy back to the hard drive from a burned DVD.
