Subscribing to Pod-cast using a link

[VaShaun Jones]

Listers this is a link that I was given to subscribe to a pod-cast,  
however when I I go to subscribe to pod-cast and put in this link it  
just shows the link in the songs table under pod-cast. I know how to  
subscribe using search in the I Tunes store, but this way has me  
stumped. Can someone direct me as to what I am doing wrong? The link  
is http://phobos.apple.com/WebObjects/MZStore.woa/wa/viewPodcast?id=250474344
