Hey Scott,
I just took a look at that downloader. It appears to do the same thing that
TwitchTools does. Twitch/Justin both break up streams into 30-minute FLV chunks and I think TwitchTools handles this better. It actually gives you the links to each chunk but it looks like the Justin downloader only gives you first 30-minute chunk...you have to figure out the URLs for remaining chunks on your own.
You can actually download Justin videos using TwitchTools. You just need to replace "justin" in the URL with "twitch." For example, I downloaded George's recent broadcast by changing "www.
justin.tv/dk3champ/b/503031559" to "www.
twitch.tv/dk3champ/b/503031559."
With all that said, there doesn't seem to be any audio in FLV files I downloaded from either site and I'm not sure what to do about that.
