DVDs on Xbox

[gibs]

Hi all,

(Think I may have posted earlier in the wrong section, so hoping you might be able to help me.

I have burned various backup DVDs however they only do not play on my Xbox. My Xbox has been modded with a Matrix chip, and the DVDs play on all other stand alone systems.

I have tried various different media, burned it as UDF, used Nero and PromoDVD but still they do not work.

I am using DVD Region X player on my Xbox.

Any help would be greatly appreciated!
