This can be found on the SciFi Channel's BSG website, but is likely blocked to anyone not in the U.S.
It is a short video that summarizes the entire Battlestar series to date.
It's fairly complete, fast paced, insightful, and fraking funny to boot.
Raw FLV ripped from SciFi's website, black borders cropped, and re-encoded to Xvid which is just easier to play.
It already looked pretty bad, but not much quality was lost. If you prefer I've also uploaded the raw flv here: http://www.mininova.org/tor/1283935
Video: Xvid, 742kbps, 29.97p (they did that unfortunately), 384x224
Audio: MP3 44khz, 48kbps (untouched)
