5.1 surround channel coupling
It obviously would be nice to have such a mode available, for e.g. DVD audio compression. Apparently, the list doesn''t tell me too much about it. My questions are: 1.

If I''ll be interested in participation in its development, what is the recommended reading? -------------- next part -------------- An HTML

Would anyone like a

[1.1.1] Too much quantization on flat red surfaces
Hi, I've tested Theora on an HD-ready material, with quality 7, single pass. Resulting bitrate was 1.8Mb/s. Most parts of a movie encoded this way look fine, usually better than a DVD, and in daylight scenes, have no noticeable artifacts at all. But it seems that red surfaces are too much compressed; blocking artifacts are clearly visible on them. Also, white people have slightly smeared
