Ok this is what you need to do...
First watch the whole episode at www.icebox.com,
if you dont want to watch it do something else while its showing. Then once the episode has shown, go to 'Temporary Internet Files' and search "SWF" make sure you can see how big the files are, all of the ZC epsidoe are atlest 1.50MB. Then drag them to any folder you wont, or just take them to your desktop and open them with a browser (the internet). Thats it, rename them so you can figure out with episode they are and thats it.
Hope this helped.
If you dont know where the temp folder is, go to internet options, its there somewhere
