Yes, Czech TV. That's the one (in the list provided above), streaming all GPs this season. They usualy don't show GP though, sometimes GPF and Euro + Worlds of course. I guess it's because Uncle Brez is skating and FS is somewhat popular here for decades.
Sadly, Czech commentary can be a bit... how to put it... our commentators are usually very neutral, often don't know much about skaters. The only time I've heard someone praising Yuzuru without any "but", was last Worlds Gala. Even with other skaters, I think our commentators are just careful not to praise any "non-Czech" skaters too much.
I have no idea, if it is possible to watch without commentary, or if it is blocked, but I guess, since it is Czech TV, it will be accessible only locally.
