I’ve spent the entire day trying to download someone else’s recorded Ustream vid and nothing is working. I’ve downloaded tons of .flv programs and had to uninstall them because none of them worked. I’ve used most of the url sniffers as well and they failed too. Is this even possible?
You could use something like DownloadHelper (a free Firefox addon) or RealPlayer Downloader. Both will convert your files to other formats if you so choose.
I have used Super to convert media files on my PC and it says:
SUPER © also plays and saves Internet Media Streams of different protocols
What you are trying to do is against the terms and conditions of use for Ustream. If UStream wanted you to download their content they’d provide the facility to do so.
