in that case you can safely ignore my question ;-)
best way forward would be to do a trial & error session, starting out with JS autoptimization active and as little excludes as possible. I was thinking:
jquery.vaccordion.js,
vaccordion.js,
jquery.nivo.slider.pack.js,
nivo.slider.pack.js,
or maybe even only either vaccordion or nivo.slider, to begin with?
Configure this and take a look at the page AND at the error console, which will probably complain about some javascript-problems. If you want I'm willing to have a look at your page at that point as well (but your site would be broken during that time).
The goal is to, based on the error-messages (and your knowledge of what you're using to have the slider displayed) identify just those javascript-requests that have to be excluded.
