Our media help page provides a half dozen players with Theora support.

Windows also does not support SVG natively, IE renders PNG with
transparency wrong (at least I think it still does). There was also a
time when Windows included no support for MP3. Windows 2000 didn't
ship with an MPEG4 codec, and I don't think that XP does either
(although it will happily download one).

A huge amount of streaming video on the Web requires codec downloads,
but Windows Media player will autodownload most of them, although it
will not autodownload theora this is why the en vogue video glurge
sites use flash based players.

If you want mostly painless universial support for Windows users, what
you should be arguing for is a java Wikipedia player (which is
certantly possible).

And the mediawiki code that Wikipedia usually runs is labeled 'beta'. 
Can you point out any discussion about bugs in Theora?

The code is quite sold and has been for a long time.

To where?  They aren't arriving in mass in OTRS.

It might have been more useful to begin the discussion on the media
help talk page.

If our instructions are too complex then they should be improved. I
think they are pretty easy as is: most of the software is a single
click to install and then both Theora and Vorbis just work when you
click on them.

We haven't even managed to get all of the mp3 files off of english
Wikipedia yet and they've been forbidden for a long time now, so I
can't see how your proposed change would accomplish anything except
forcing our users to use patent encumbered formats.

Also, as the single largest uploader of original music recordings
(although it's still a pretty limited number because the annoyance of
copyright issues on music is keeping me from uploading hundreds of
tracks), I'd like to also voice another objection: I strongly oppose
the use of the content I've created to promote patent encumbered
formats.

The RIFF wrapper used for most of the microsoft formats is a
multiformat wrapper (Just like OGG) and can happily be coerced into
containing executable code (unlike OGG).

Both are only available under obnoxious patent licenses which claim to
demand fees per download, and otherwise control the creators,
distributors, and users of the content.

'Mode widely used' is a broken argument by itself. If we were going
for most widely used, for revision controlled text we'd be using
Microsoft Word rather than Wikitext.
