| Greek Wedding it was 69% smaller.  Those are large numbers.  And the

| 288 kbps nominal bitrate.  But most of the time it was well below 130
| kbps.  In fact Matrix averaged 162 kbps and My Big Fat Greek Wedding
| averaged in at 121 kbps.  That's 5.1 surround at or below bitrates most

| mp3 or even 192kbit mp3.

Once again, pardon the n00b... what does Quality 0 mean? How do I get
oggmachine to use it? Thanks for the help, once again.
