[theora] Video Comparison

the Theora videos look good and play quite well under Ubuntu 9.10 with 
Firefox 3.5.7. Also CPU load is smaller while playing the Theora videos.

I would be interested if you transcoded from some raw videos with higher 
resolution that you got from Golem.de or if you used the finished H.264 
Flash videos that can be seen online? Of course this would affect the 
resulting Theora quality.

The only problem I noticed are some glitches with the Theora videos (not 
audio) so the video didn't played as smooth as with Flash player. But I 
think it's because Firefox is new in playing videos and there is room 
for improvement.

I also don't like that online videos always prebuffer until the end. 
This could lead to some bandwidth shortage and video disruption when you 
test one video after the other without waiting long enough.

Most test material I found does not focus real live videos, so the comparison does not reflect the user experiences. So I decided to use good quality web videos. The videos on golem.de have a much better quality than nearly all videos available through youtube.
