I need a detailed guide to burning an MP4 for DVD with using Nero.

I searched previously, and I believe I got it right...but when I tried ripping it with DVD Decrypter, it said I couldn't find the VIDEO_TS file.
(I'm doing this for extra practice. I do LEGALLY own the dvd. I just want practice.)

Here's the step I did on Nero...

1. Open Nero (express)
2. Click on "Data DVD"
3. Click on Add.
4. Found my file. (it's 560MB)
5. Next.
6. There was two options... Image Recorder [DVD] and E:Phillips blahblahblah [DVD]
6a. I clicked on Phillips. Because, I thought Image Recorder = ISO?
7. Burned.

After it burned, it opend my CD tray, and I put it back in. The file was indeed ON it... Read on.

Opened up DVD Decrypter.
It gave me that mesasge "Could Not Find VIDEO_TS file" junk..

Please help.
