If you wanted to watch HD DVDs on the 360 you would have to buy the extra external HD DVD player. This does not make much sense now because HD DVDs "lost" the format war to Blu Ray.
You just put the DVD into the Xbox 360 tray close it.And injoy
Yes - though depending on where you purchased your Xbox 360, you may or may not be able to do so.Region 1 DVDs are designated to be played primarily in North America (Canada, U.S), U.S. territories, and Bermuda.If you purchased your Xbox 360 in any of these areas, you should be good.If not, you can watch it on your PC.
On a XBOX 360 u can but on a the old XBOX's i think you have to buy a thing to plug into it
no
You can open the disc tray and place the DVD in the XBOX 360 and hit Play. It will read the DVD disc and present you with an option to play your movie unless it is a burnt copy and in a ill-regular format which in this case the standard XBOX 360 drive firmware won't be able to read it.
Not sure about the original xbox.But the Xbox 360 can

No, the Xbox 360 elite only plays DVDs like all other models of xbox.
