exactly the same behaviour here.
during playback of a movie, avi, mkv etc.
pause = pauses playback and brings up the infobar with time elapsed on the left, time remaining on the right.
pressing pause or play while already paused = resumes playback from the point where it was paused.
pressing stop at any time takes you back to the play list.
p.s this is the behaviour on my Vu machines although it should be the exact same on the xtrends.
