How do I play ogg files?

You can try using this plugin:
http://xiph.org/quicktime/

If that doesn't work, you'll have to convert them to a different format using another program like Audacity:

I'm having the same problem. I've installed the Xiph component according to the README. I can open quicktime and then do File::Open, select a .ogg file, and play it.

iTunes, however, steadfastly refuses to acknowledge the existence of a .ogg file. If I add to the library a directory structure containing ogg files, they get skipped. If I start with an empty library and add a single ogg file, it's ignored. If I drag a ogg file to iTunes, nothing happens.

It's a new machine and I've installed all the updates. What am I missing?

Thanks!

Quicktime may play it, but it can be added to the iTunes library only if it is in one of the iTunes supported formats: mp3, AAC, ALE, WAV, AIFF. Convert it to one of those, then add.

I was able to add my Ogg files (FLAC-encoded in an ogg container) to iTunes just fine.

Robert, That is good to know, thanks. I assume it does not help for the iPod however? FYI I use Winamp to play OGG files.

Of course you are correct -- it will not help the iPod play the files!
