What is in the file directory that you are trying to save your DVD files to?
When you rip video from a DVD, the video files are given the same basic names: VTS_01_VOB, VTS_01_01.VOB, etc. So if you've already got files that were ripped from a DVD in the directory folder, the program will think the files you are trying to add already exist.
Assuming you're using the Video Importer (Add Media/From DVD Camera or Computer Drive) to rip the video from the disc, the easiest solution is to direct the video to be saved to a new directory folder on your computer.
If you need help doing this, check out my free 8 part Basic Training tutorials. Part 2 deals with capturing video from and AVCHD camcorder, but the process is the same if you are using the Video Importer to rip video from a DVD.
I have a similar problem. I have imported one set of VOB files from my DVD payer into Elements 15 with no problem. Now I cannot import any more. I understand that I cannot import to the same folder because all the files have the same name. I have tried sending to a new subfolder, I tried moving the originals out of the default folder, I tried sending to a new folder on a completely different hard drive, but always get the same message: Import Error. File already exists at G:\family\TEST (or wherever I try to send it)
It matters not whether this is a file I have already imported or a new one.
There is nothing in these folders - why can't I import?
I think I may have found the answer to this in a previous thread.
On the import screen, don't leave the "pre-sets" option blank - select an option from the drop-down list. That seems to solve the problem. (See the thread I,added,some,video,clips,from,a,SD,card,to,Premiere,Elements,but,when,I,tried,to,add,some, )
