What do you mean by ogg? vorbis? theora? (any video chipset that can 
decode theora or dirac, BTW?) I assume vorbis.

Like many other codecs, vorbis makes encoding a more complex and 
CPU-intensive task than decoding. So the fact that your computer 
worked so hard on encoding does not mean it'll sweat as badly when playing the song.

But then again, we add ripping a CD to the CPU-intensive tasks.

So, and back to the list of tasks that can benefit from a processor:

* Openning an ODF document
  - Opening the ZIP archive
  - Rendering forns to the screen, with many complex calculations of 
    location and size.
  - Saving the file back.
* Displaying a PNG or JPEG image
