That is a good point - although it's nice to have a multichannel Ogg file, 
they're almost always larger than the original AC3 file for various reasons.  
This will probably change in the future, but for the time being you'd only 
really do it just to see if it can be done, there aren't really any benefits 
of the conversion at the moment - you certainly wouldn't convert an AC3 file 
to an Ogg to make it smaller.

You'd probably be better off transcoding the AC3 file to a lower bitrate if 
you need to make it smaller (if that's possible - I've never tried it 
before!)

Cheers,
Adam.
