xbox 360 question

hi guys quick question i have my xbox hooked up to a HD 26" widescreen flat pannel TV. I have the switch flipped for HD and it also switch in the settings on the xbox it self. SO this means all my games i play are in HD? also are the dvd’s i play in it in HD now as well?
-i’m using the componet cables into the ports inthe back of hte tv. is all of this correct?

i dont think so thats what the aftermarket dvd player is for its 99$ for the xbox dvd player not bad matches the 360

no you have to get the hd dvd addon player, its 199.00
