I'll try to answer some of this. If you sit down at the computer at 2pm for example you can watch it live or drag it back and watch it from the beginning. That way if there is a class you don't care for you can drag forward. You are watching it and listen to the track announcer. If watching live you are just like the person at the track, watching the track be cleaned up, rain delay, ect, ect. You can also watch races from other years with your subscription and once in awhile they add an older vintage race.
