It contains video in MP4 format.

How can I achieve that?

CDs and DVDs come in two flavors: CD-R, DVD-R and CD-RW, DVD-RW.

The RW means you can keep clearing and writing to them. The R means you can only do this once.

So the simple answer is: just use a CD-R or DVD-R (or DVD+R) and write to it once, then it is read-only by default.

AFH makes a good point: If you make the CD/DVD a data disk that you can write to from your Windows Explorer, then you also need to finalize the disk at the end. If you use a burning program and write it all, by default the checkmark to finalize the disk is already enabled.
