In think we have different ver of PE in my 11 the screen looks like below unless I'm in the wrong place
path was publish share/computer/ MPEG/Advanced (turned export video) scrolled down.
I think the 44.1 / 48 thing might be moot anyway cause if PE uses 48 then I should stay with that which is easy for me to do
I'm going to do a test in a few days . . . . . .
