"p" stands for progressive and "i" stands for interlaced. 1080i is only used for broadcast television, as far as I know. If Ady is using a Blu-Ray source, than it will be 1080p. Hope that helps. :)

Yeah that was helpfull thanks so much...I'm just starting in my video editing adventure so I have a lot to learn. Im using vegas pro 9, adobe after effects CS3, FX home and Magix movie edit pro 15...now its time to figure all this stuff out....(takes a really deep breath). I really hope the investment pays off...:-)
