[theora-codecs] setting things right (side up)

[Blibbler]

Why is losslessly transcoding VP3 to Theora so important? I have quite 
a few VP3 vids around however, and it would be great to be able to 
convert them to Theora without having to re-encode them, however I 
don't understand why it should be a major requirement. Very few people 
will want to migrate their videos from VP3 to Theora.
