Well - there were some serious offers in the ML to help out..

hmm.. These are ~606 kBit/s and I guess there is audio included. If you 
use a 64 kBit/s OGG Vorbis audio compression you have ~540 kBit/s left 
for the video stream. So I expect these videos will be VERY good 
quality! The usage of the open source XVID codec would have been much 
better as it offers the same features as DivX 6, e.g. B-frames etc.
What resolution do you use? The full PAL 720x576, maybe converted to 1:1 
VGA pixel aspect ratio (756x576)?

Which deinterlacing methode do you use?

- Weaving
- Bobbing
- Blending or
- Adaptive?

So here we have got ~90 kBit/s, which I call a really good bandwidth. I 
am looking forward to see the results.
BTW - Windows media encoder has a very good built-in deinterlacer, so 
you can deinterlace on the fly.

Anyway - great job - the videos are VERY interesting, if you have not 
been at the Tycon and its really great they are released to the public! 
I really like Kaspers keynote, because it really gave answers to some 
questions I had in mind about the way Typo3 develops at the moment and 
in the future.
