It may be possible for the spinervals videos to control a trainer but I'm not sure. The way they work is you get on your bike and pedal your a$$ off while Coach Troy tells you what to do . Seriously though, he'll guide you through the workout by saying such things as "Change to big chain ring", "Shift down two gears", etc. On the screen you'll see a timer of accumulated workout time and a count down timer for the current exercise set. They are great!
