You can download videos from off of youtube- not through youtube itself but by using third party websites that parse youtube links and return a download link.

example: savevid.com

I typically download videos so I don't have to visit youtube every time i want to watch them- they are *.mp4 (mpeg 4 container format) files that play fine in media player (winamp still wont play video mp4 files, only the audio). You can always convert them using software like mpeg4maker (which wasn't free- well the watermark version is).

Anyways, download important videos like this one next time so you could always repost them yourself with your own youtube account.

And yes, I have a growing collection of darkfall videos on my pc including the "revenge on dominion" video but i didn't get around to downloading the original video in the OP.

The following videos are my favorites
Darkfall - Sunthrone raid 9_12_09 Part 1
Darkfall - Sunthrone raid 9_12_09 Part 2

So off topic- anyways, download videos like that one next time before they have a chance to remove them.
