For anyone that wants to watch horse racing on their Roku or computer that can't or doesn't want to get TVG, RTN is great.

I believe the only tracks you can't watch on the Internet/Roku Version are Churchill Downs, Fairgrounds, and Arlington Park.
The tracks that broadcast HD Signals are available in HD.
Lots of fun. Nothing is more fun than spending a Saturday afternoon at home watching HD horse racing on a big screen tv.
