That is quite a dramatic difference, and does but a lot of other metrics in a new light - be it total number of streams or share of users playing video. It will be interesting to see if they keep publishing this kind of detailed breakdown or simply revert to the average and total numbers again.
Also, the pressrelase list some (for me at least) new sites that are apparently a big draw in the 'heavy' crowd - might be worth a look (not linking since I haven't seen the sites or their brand of content/ads yet):
- Ouou.com
- MegaVideo.com
- Youku.com
- zSHARE
- Tudou.com
