[theora] Extension .v+ogg does work

[Charles Iliya Krempeaux]

Hello,

Sorry if this too has been discussed many times already, but....

(Assuming there is one....)  What's the argument against also registering
MIME types like "video/ogg" and "audio/ogg" (instead of just giving
everything a "application/ogg" extension)?


See ya
