I suppose I'll have to re-download the iso if the md5sum doesn't match 
(which it doesn't per <https://help.ubuntu.com/community/
UbuntuHashes#9.04>)?  The problem is that the iso is corrupted?

thufir@arrakis:~/Desktop$ sudo mount -o loop ~/Desktop/ubuntu-9.04-
alternate-i386.iso /media/cdrom0
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

thufir@arrakis:~/Desktop$ sudo e2fsck -yv /dev/sda1
[sudo] password for thufir: 
e2fsck 1.41.3 (12-Oct-2008)
/dev/sda1 is mounted.  

WARNING!!!  Running e2fsck on a mounted filesystem may cause
SEVERE filesystem damage.

Do you really want to continue (y/n)? no

check aborted.
thufir@arrakis:~/Desktop$ 


I wasn't quite sure how to run fsck without a live cd...

out of curiosity, when I tried to download via the torrent the speed 
seemed exactly the same as directly downloading the iso but the progress 
was painfully slow versus directly downloading the CD (which I'll do 
again).


thanks,

Thufir

Do the md5sums match?  If they do you downloaded the cd fine.  If not,
redownload

You need to grab the md5sum file and run md5sum -c (md5sumfile)

What is /dev/sda1?  On most of my machines that's boot, although I won't
assume anything.  Also, I believe you can mount stuff read only via
mount -o ro,remount <mountpoint> and fsck will be *much* happier.

Torrents speeds are based on your peers and isps.  Downloads the
traditional ways are direct connections to one server.  Torrents should
be faster but ISPs throttle you quite frequently. I hope this answered
everything :)
