Smoothing out lookto on my first pano

My first attempt at creating a pano/tour:

http://outridercreative.com/development/pano/

I added an action to onstart:

oninterrupt(break); 
wait(2); 
lookto(-52,12,80,smooth(60,60,60));

...but when the browser pans across the scene, I see "hiccups" or skips. It is not smooth. The same problem happens when you click the link to the next pano (which is actually the same pano.)

I added this code, but it does not help:

<display movequality="LOW" stillquality="HIGHSHARP" />

Can you please help me smooth out these transitions?

how do you get this link??

it's hidden in the code that Youtube provides when you click the "embed" button. Youtube forces you to copy the whole embed link, but if you paste it into notepad, you can isolate that URL.
