This is nuts! Gspot worked, but why must I run around the internet
installing .exe install files to get codecs when media player always used
to install codecs automatically? What has changed?
Because Windows Media Player will only automatically download *Microsoft*
codecs. (And a few approved others.) And if you have WMP9 (and if you have
sp2, you do), then you already have all of Microsoft's codecs. (Except for
the Indeo codecs, which were removed in newer versions of XP.)
And Microsoft no longer does new AVI codecs. They do WMV and WMA codecs now
because that's their prefered format. (There are some significant
limitations to avi, actually.)
The only Microsoft AVI codecs around are the old ones. The ones from Win95
and Win98 days.
The reality is you probably already have those old codecs. But few people
use them because they are so low quality.
Instead they'll use newer stuff. Such as Divx, Divx3, and a whole bunch of
others. (Although some use older ones, because they don't know any better.)
But since they aren't Microsoft's codecs, you can't get them from Microsoft.
(Well, I think you can get a few non-microsoft ones there, but not the more
popular current ones.)
There is no 'official' codec repository. Microsoft sort of tried to do that
by having wmp check microsoft.com, but they didn't really do it well and
don't maintain it. (If WMP can't even go there and check, and
automatically download required codecs, you probably have it disabled and
perhaps blocked by your firewall.)
It is indeed a mess. That's why utilities like gspot etc. exist.
AVI was designed to be a generic audio video container, but no real way was
developed to handle the large number of codecs the user might encounter.
(Remember, avi was developed many many years ago. I think Win3 had it. It
was certainly in Win95.)
Windows Media Player can check Microsoft and see what's there. But since
they aren't Microsoft codecs, you can't get most of them there.
The user is usually on their own.
That's also why some people install those warez "codec packs", which contain
a lot of codecs that you might possibly need. However I strongly recommend
against those because they are warez. You've got no idea what else they
might be doing. They might not even be correctly doing what they claim they
are doing.
