I used to be on here under the handle Megadeus324. I messed something up and had to register again, which was a good thing. I needed, at the time of registration, to ask a question about a DVD backup I made BUT the one day wait was worth it, I figured my problem out on my own and here is the short story of it:

I had backed up a DVD using DVDDecrypter. There was the widescreen and regular screen vob's and ifo's. I selected the files which I thought were the correct ones, they weren't.

As soon as I wanted to burn this backup with Nero I received an error message stating that the burned dvd "May Not PLay" as there was a problem with the files.

I researched this topic and found out I had backed up the wrong ifo. So, I was on a "How to create a new IFO" hunt. I found IfoEdit and DVDFab.

Now, to make a long story short, I think IfoEdit was "too" easy for me to figure out, which, I couldn't. So, I used DVDFab and within 30 minutes my backed up dvd was playing on my player.

So, if anyone has any problems with no IFO's or needs to fix them, try this DVDFab. It is great by my book.
