XDVDMulleter- No Video File Found Error

I have a backed up xbox 1 game (made for the xbox 1 console on a single layer DVD) that I am trying to get working on a flashed xbox 360. From what I have found, the game needs to be rebuild to be a DVD9 using Xdvdmulleter which there are plenty of tutorials for around the web. I have a Kreon Drive so I am able to get all the required DMI, PFI and SS files.

The problem I am having is that every time I go to make the ISO, XDVDMulleter comes up with "no video file found " error and does not do anything. I have tried using the insert video feature of XDVDMulleter in the View ISO Details menu but it still come up with the same error.

I have searched everywhere and still have not found a solution to this problem. I have read other people having the same issue and fixing it but they don't say how. If any knows anyway to fix this it will be much appreciated!

I am using XDVDMulleter Beta 10 and as I said before, I have a Kreon Drive.

Thanks.
