If you have one of the newer DVR's connected to the internet it can be accessed that way.
Is it a DirecTV channel? No and I never claimed it to be. I said Speed 2, a simple Google Search would have turned up -
SPEED2 is a brand new authenticated broadband-delivered video network focused on motorsports competition and automobile & motorcycle enthusiast programming. SPEED has more racing series and motorsports enthusiast programming that can fit on a single TV network, so SPEED2 was created as a dedicated broadband platform to deliver an expanded variety of racing, featuring popular international events from around the world.
I use DirecTV with a HTPC so it really doesn't matter... I can access it on my "TV" or my computer(s).
