Does this mean that play once forward will seek out the last frame ond play one forward and stop at that frame autimatically, or will we have to jump in and out of hud mode to find the frame and set it?

IMHO, I vote for the easiest way which is to play once without it flipping back to the last frame, without having to go through the steps of setting out points, otherwise you might as well always play forward then build a stop cue to stop the video at the end. A mode that plays once based on in and out points would be good too, but as a separate mode.

Just my 2c.
