Layout for a DVD2One Movie on disc

[3rdDegreeBurns]

I recently burned a movie after following all of the instructions in the "Menus/Extras" guide on DVD2DVDR.com using DVD decryper, DVD2One, MAkeItEasy, and IFOEdit etc. I found that my VOB files were correctly sized and played correctly if I navigated to them through the PC but I could no start the DVD as normal - it would say unknown file format.

Obviously it doesn't recognize my disc as a dvd-movie. Is this because I used only a VIDEO_TS folder and not an AUDIO_TS one...I wasn't sure whether to because on the original DVD i only saw a VIDEO_TS folder and I wasn't sure that I had any files that were audio...Can anyone explain how this process works and what i need to do in future?
