im not sure what you mean by bing, its a search engine
if you mean to capture vids sorta like streaming you can use many tools
i just use fraps and a freemake video convert
to push the raw format to avi,
but there are easier ways esp if its in temp or cache
u can just copy it on over.
btw nameless if you dont have fraps, just google how do i dl vids from bing, mighta been worth a look
