Do a search on ClassRacer. A number of conversations about it have been had there. It's far from being "bug" free or totally inclusive of sportsman racing. It's basically the announcing deck and video feed from a national event.

If you have time to sit and watch, it's OK, I don't. I used to listen to the audio feed from the national events when it was part of the membership package. I'd have that on all weekend and was pissed when they eliminated it and replaced it with what they have now. I do like the D1TV and DragracerTV feeds from most divisional events and will typically have them on in the shop whenever they are running one, which is most every weekend during the summer.

Plenty of other stuff to chose from, drag radial events, NMCA, PDRA which I really like - all free.
