Thanks guys for your help... I've changed my Firewall Config. to 80 which has helped a little. I've noticed the download speeds seem to rise to as much as 20 KB/s and then drop to 1 KB/s on a regular basis... almost like it's pulsating. I guess you just need to be patient.
The files I'm downloading are mainly the American Chopper series though the episodes I'm having trouble with are the rare ones.
