Read this VERY carefully
i have read about this question too many times.
i try to explain what the truth behind this.
ideally, same data on different CD/DVD must be the same, independently to burner/media/reader, because the bits wouldn't need to be "interpreted" but would be read only like they're EXACTLY are, so a zero is a 0 and cannot be read as a 1, 0.534 or as a 1.25, and so on, and the same applies to one's..
reality is far away.
CD and DVDs are made of so-called pits and lands: these are short and long traces written on the media, made by an intermitting laser.
the positions of these traces are FAR from perfect, because of many factors, so they can ie. be a little longer/shorter or have a bad position.
however there is a standard interval, in which these imperfections HAVE TO fall, so they can be read EXACTLY.
this leads to the fact that writing with a worse media, or with a less precise writer, or with a higher speed, make these little traces less precise, so it's more difficult for a reader to interpret 0s and 1s EXACTLY.
if a zero is written very badly, it can appear like a one, an cause an error.

evidently, your DVD aren't burned very well, or xbox isn't a very good reader.
