FYI I just discovered that this stuff was being aired this morning, watching the 2010 national enduro race from Lubbock right now in HD on channel 361 from Dish network satellite TV. Not sure what other providers offer this channel. http://www.mavtv.com/shows/ama-2010-racing-series
MavTV has been truly impressive as of late. I watched the Texas GNCC in full hi-def... at least that is what they kept calling it.
