Yes you can play an avi file and I don't think ther is a limit with the resolution. Then for the power, the better computer you will use the better results you will get.
OK so i have been trying to do this and cant figure it out
how would i make a avi button or something like that but keep in mind i cant use time lines in EC
ok thanks bruno.falip
that worked
but my new problem is that i get audio but the video is black unless i move the window (nuge it a little ) then the video apears and plays fine but in full screen mode its black and i cant nuge it since its full screen
