I'm having problems with my Roku streaming Live videos too. Same issue as above. Thanks for the advice of hitting play a few times--my video worked after hitting play 5 times. Hopefully this issue gets resolved soon!
I had the suspended "wood" aerobic floor installed in my workout room last year and it was the best purchase I've made in a long time. My knees were really beginning to bother me after doing the high impact moves on Cathe's videos with my old floor. My knee pain went away almost immediately...
