I tried with this options but keyboard strokes are catched by mgp...
However without +Zp1, the animation is shown, but only some
frame are visualized (4 or 5 of 20)
I noticed that this behaviour is performed by xanim even
outside mgp...

*Why?*

mpeg_play, instead, shows all the 20 frames (outside mgp):
this was the reason why I wanted to use mpeg_play...

I don't know why, but, as I said, keystrokes are ineffective
in mgp environment (they are interpreted as mgp commands and
don't seem to reach xanim).
