If you are using a non sky box, then scan frequency

11681V/27500
Setanta Sport(51111) – currently showing GP2
Setanta Sport1(51112) – live rugby sevens
Premiere Sport(51113, 51115) – same as MSK (433) on sky box with UK settings but much better quality!

Due to a frequency shuffle around, these channels are currently free to air – someones not flicked the correct switch at the moment.

No idea for how long.

They are still blocked on a sky box.
