OK, no one is going to give up on you, however, please answer the questions asked instead of scooting around them.
I can see now that you are trying to burn a file type that ImgBurn does not support.
So, here is your easiest option. (In my opinion).
If you have a programme called DVD SHRINK installed, use that, if you don't, get it (It's free) and get it to output the file to an ISO format.
You will find this option in the drop down menu when you hit "backup", (the last step)
This will output all those files you are trying to burn to one large file (the combination of all the VOB's, IFO's, BUP's) with an ISO extension, Something like NAMEOFDVD.ISO.
Now you can burn the above said with ImgBurn.
Good luck.
Here you go FARMER - this is the bit of Ken's post that you need, grab shrink and use that, there are plenty of guides to be found via Google for that piece of software. Also you can read up and get advice on Shrink at http://forum.digital-digest.com/
Hope this helps, as Ken said (very subtle !! ) we have to be careful here as we can only help you burn images, how you get them is more problematic as it involves various laws depending on where you live and we don't take any chances here.....
