How can you edit the Video Bar for Blogger blogs?

I'm using this video bar on my blog:


http://www.google.com/uds/solutions/vide...


and i'm using the vertical bar - but I don't want to have like 8 videos on my side bar - I'd much prefer for it to just display 4.


Does anyone know how to edit the code so it only displays 4?





Thank you muchly.

Interestingly, it seems from the documentation there is no way to limit the number of results returned.
