so i just got a new lcd tv too thats 1080p and i was looking at the bundle information and it says

” Includes: Xbox 360 Composite A/V cable: Maximize your Xbox 360 picture quality on standard-definition televisions using this S-Video connection for a noticeable image improvement over traditional composite”

my question is.. is the cord the modern warfare bundle comes with HDMI? cause my tv’s 1080p and i wanna play in 1080p..

another question.. so theres 2 types cords theres one thats just hdmi and one thats hdmi + av cable.. so its hd graphics + offers better sound quality…. if i get the hdmi+ av cable, can i just plug the hdmi+av cable cord for just hdmi graphics n not sound?

1 more question.. i was looking at this

does this modern warfare pack not come with the composite a/v cable and extra controller? cause i was looking at the info doesn’t say anything about a composite a/v cable included and a extra controller.
