If you are deeply studying just a few horses, the rtn.tv (or on your satellite, cable or Roku streamer) is, by far the best, as you can select high quality video replays (same as remote feeds) for ANYTHING. If you want to look up the last 50 races that Horse XYZ has been in, you can do it. If you want to look at a single race, any track, it is there (full screen). If you want to watch an entire program from a track, go get it. They have everything easily sorted and go back several years. You can keep tabs on specific horses, as it will learn the ones you repeatedly want replays for. You can tailor your subscription (and the price) to exactly what you want. By far my most valuable handicapping and also horse-buying tool. Horse listed on Ongait or Preferred Equine Online, don't just look up racelines, but WATCH every/any race of his/her you want going back as far as you want. Watch them up close (equipment, gait, drivers, etc.) NO, I don't get any commission ;>>)
