I've tried at my house and another house in a different state. I can go through internet and find it. It plays for a minute and kicks off, loads,plays for a short time and kicks off. Both times on Smart TV's and cable with wireless. The Youtube Motormania works great. What's up with Speed Video?

In the past I've used the Livestream app to stream speedvideo to my chromecast with good results.

Do you have to subscribe and or pay for the App? I don't find the App on my Samsung TV. I think I can get it through my Roku on my old TV.

The Livestream app is free on Android and Apple if your TV has streaming capability. Roku does have the Livestream app as well

I give up on my Samsung, I can watch it on my old TV with the Roku.

Works okay on web browser here.

I use the livestream app on Roku to watch speedvideo and motormania tv.
