Hey all, I have followed a thread on golem.de, which was about an article regarding mozillas reasons, not to include h264 and to prefere theora instead. In the forum there was much talking about a lot of nonsens (as usual). But there is still a huge and loud number of people believing that theora has a significant worse quality compared to h264.
