I don't have a personal grudge against theora or anything.  It's just that,
at any given bit rate, the visual quality it delivers is comparable to that
of MPEG1.  If that is good enough for you, fine.  It's not good enough for

I don't understand what you're trying to say there.

Yes, On2 has given permission to use the vp3 related patents that it holds.
Doing anything more advanced is highly likely to infringe on some patent.
I don't like it that way at all, but a fundamentally altering the US patent

Besides, this patent talk is irrelevant when talking about pure visual
quality delivered by a codec.
