Invisible Disc(blade trinity&National Treasure)

yo peeps wats am giving a holla fromjamaica

i recently obtained a copy of blade trinity and national treasure
but when i put them in the burners at home the drive does not reconize the dvd is theis a new form of copy protection

but funny enough it plays on my xbox

its possible that its just not compatible with the dvd player from your computer. did both these discs come from the same source? and are they dvd-/+r’s? or orginals?

both disc are originals both burners are plus and minus

same probs here
