Motherwell are streaming it on their own PPV channel for £10. You will need to sign up for an account but once you have done that you can login,purchase a pass and watch the stream when it goes live (usually between 15-30mins before kick off).

The quality is a bit mixed. Last season was a bit of a mess at the start due to it only being introduced (the wee "we'll be back" Lady still gives me nightmares some nights) but it has progressed to meh or alright quality. Not as well produced as sky or even Premier Sports but it is mostly viewable. Sometimes, if the away team chooses, there can be an away team link that would have thier own commentators commentating on the stream.
