Oggetto: External linking only?


Hello,
i'm trying to do an interactive presentation with something like a menu and
i wish to show the section elements according on what user choose from menu,
and then have the chance to get back to menu.
The question is: is it possible only creating external href to other smil
files?
I wanted to have a background soundtrack that keep playing wherever the user
is, if i use external href i couldn't keep the soundtrack playing (or at
least i have to restart it always).
I tried to use one file to achieve what i need, without success. I put the
menu elements into a <par> group and then i expect they stop when the <par>
group end and they start again when the <par> is started again.
But it acts weird: the following code hide the par1 elements and show
section1 image, but when i click on section1 i would expect that par1
elements restarts as first time: they don't. Petal starts at the same time
and after a little while every element of par1 disappear.

Anybody can help me understanding how interactive presentations works? Any
code example would be much appreciated, it's 3 days i'm googling around and
couldn't find a decente interactive example. Thanks.
