Tomas - ignore that list, it just tells you what is on at a certain time. You need to click on the Channel on the right of the page. For instance click on Sky Sports 1 now and you will see live rugby
I think you still need a TV guide before viewing Premium TV . Then select the appropriate channel on the right hand side. Good quality pictures there usually
Some of the other sites list the sport or the match which you click on to view.
