On your ATV2, go to Internet > Podcasts. Look for a Podcast series from Apple named "Apple Keynotes". It has all of the Keynotes and Special Events from Apple dating back to 2007. Excellent quality too. Save the Podcast series to your favorites for easy access in the future. Thought I would bring this to your attention because apparently not a lot of people are aware of all the free goodness on the Apple TV in the Podcasts feature. You can also subscribe to the podcast in iTunes and watch through Home Sharing but I find the built in ATV Podcast streaming feature easier for stuff like this.
