[Theora] mpeg4/xvid/divx vs. theora

[Thomas Kuglitsch]

Hi there,

I have an elementary question.
Although theora can be placed in the same class of codecs as MPEG-1, -2, -4
why is there no greater usage of this codec?
On the bigger part of web sites trailers or short videos are encoded with
some mpeg codec. Why is theora still so rarely used and unfamiliar although
it perfomes very well from my point of view?

Is it, because
- the whole mpeg family is already included in a great bunch of hardware?
- theora can not be used that easily like mpeg on M$ OSs?
- it is still a alpha version?

Any comments on my identified reasons?

Do you encounter any other reasons?

greez,
Tom
