BT Sport Extra arrives, via the Red button

If you are one of the few Virgin Media customers who still believes you are being short changed on the amount of sports channels we have, good news - another one is on the way.
TiVo owners with a BT Sport subscription can now get the new BT Sport Extra channel for no additional cost. (Media Boy is reporting it's now working on non-TiVo boxes too.)
The new BT Sport channel, which includes coverage of games from the Bundesliga, Ligue 1, Primera Liga and Brasileirao, can be accessed when watching either BT Sport 1 or BT Sport 2 via the Red button - you’ll need to head to BT Sport 1 and 2 at channel 547 and channel 548, BT Sport 1 HD on channel 549 and BT Sport 2 HD on channel 550 and hit the Red button.
It's not in high definition (I don't think any of the red button channels are) and the line up is hardly mass audience, but it will no doubt appeal to some.
