Watching ITVN thru a TV tuner or by other means....

Hey guys,I'm a big soccer fan and I'm thinking about getting a service called ITVN. It's IPTV and it allows me to watch setanta sports (a channel I really want). The reciever has one ethernet port and a number of inputs. I was wondering if i got a tv tuner for my pc that had component input if I would be able to watch my ITVN on my computer monitor through my PC.Because I am using the spare inputs on my monitor for other things, I think this would be the only viable solution. I do however have a spare compter monitor that I would prefer not to use. It has dvi and vga ports.The link to the ITVN site and Reciever: http://www.itvn.com/support.htmlIf you guys could help me out, I would be grateful. If you have the patience, you could find a good tuner for this situation, but I should be fine...
