question about vidmaster challenge annual achievement in halo 3?

[slayer6577]

My first question is... does everyone have to be on separate 360 to do this or can you only have two 360 with everyone signed in to live? Second question is... If you would like to help and also receive this achievement add me to your friends list and leave a comment saying you want to help with this achievement. My gamertag is SLAYER6577. Thank you.
