latest ubuntu cd

[MICHAEL WEAVER <michaelweaver1 btinternet com>]

I have downloaded and burned 2 CDs of the latest Ubuntu Edgy.
One from the Ubuntu site and the other from the daily build suggested by 
Henrik.
I checked them with the ls command and it seems I may have thrown away 
CDs that may have burned because all the files seem to be there looking 
at the disks with the ls command when someone told me how to ls on a 
CDROM this morning.
However neither CD seems to list Orca.
I checked under programs and found only 6 files ie firefox but still 
couldn't find it.
Which directory should I be looking under to see if the latest Orca is 
there?
