Re: Real SMIL code question.

Hi Rich,
<seq> time container requires all its children must be definite. I think if 
your video are streaming, the rp can't detect the duration of video so they 
are indefinite that bring about the indefinite of the par1, par3, par4 and 
par5.
In this case you try to use the relative time relationship between the <par> 
time containers as following:

<par id="p1" >
    ...
</par>
<par id="p2" begin="p1.end">
    ...
</par>
<par id="p3" begin="p2.end">
    ...
</par>
<par id="p4" begin="p3.end">
    ...
</par>
<par id="p5" begin="p4.end">
    ...
</par>

hope this helps,
Tien
