I am buying a 360 and a 1080p television very soon. I have a windows media center pc. It is my understanding that you can play videos from your pc through your 360 onto your tv. If I have a 1080p movie trailer and I wanted to watch it on my tv then could I play it on my tv through my 360. I understand that the 360 can do 1080p but i guess it has to be upscaled and isn't native like bluray. Basically the question is... will the trailer play at FULL 1080p bluray quality on my tv or will the 360 screw it up and turn it into an upscaled 720p or 1080i. It would be really helpful if someone could explain this to me because if i could play downloaded movies through my 360 on my tv at this resolution then that would be awesome and would be like having a bluray player.
