Burned movie displays text over everything

[df]

I edited some video for my daughter's drama class and burned a disk for her.
When my daughter presented for the class on her teacher's computer there was text covering the video that seemingly had nothing to do with the video. I can't reproduce it and I don't even know what kind of system the teacher uses, but is there some trick to burning a disk so that it displays the same on anything and everything?

Thanks

First thing I would do Dan is play that disc on as many different computers as you can get your hands on - if none of them display this text then the fault lies with the teachers computer and not your discs. Do you know what the text said - that may help pinpoint the problem - for instance does it say something like "Unregistered DVD player" - that would certainly indicate where the problem was.
