Trouble with the FTP download of a debian CD image

["Individual . ." <individual@mi-mail.cl>]

I've been trying to download potato (an iso image of around 630 MB) 
from ftp.stealth.net.
My ftp client supports resuming, and the server does too.
Twice, with different clients, I have waited for the file to download 
to finish, only to watch in horror as the filesize climbs past the 
size it should be, the "Time Remaining" stays stuck at zero and the 
tranfer speed stays up at a high (realistically varying) number.
 In the finder the file I'm downoading is now at 750 MB and this 
clearly means that its another night completely wasted.

I will try another FTP site, maybe I should have done that for the 
second try, but this still seems ludicrous.

Has anyone had this problem before?

Thanx

Paul.
