I'd honestly rather steer away from semantics and just go with the obvious. Does it play *.avi files out of the box or not? If so, the OP is wrong. If not, then his statement stands. Not some massaged version of an *.avi either. Plan, vanilla, *.avi that anybody here could test on their N900 since I don't have one, waiting to see how the update pattern will shake out first.
