I couldn't disagree more - Trackside is a load of crap, with equally crap presenters.
With Oz Sky Racing you get 3 channels - Sky Racing 1 and 2 which caters for those who want non-stop back-to-back races (all codes), and Sky Racing World, which focuses on 2, 3 or sometimes 4 thoroughbred meetings (depending upon the day), with previews of each runner, pre- and post-race interviews. In all cases results are shown pretty much immediately. Oh, and you don't get those stupid bloody blinds covering the screen whilst the horses are loading into the barriers. It's light-years ahead of that Trackside rubbish. TVN is ok, but their coverage is limited, and the presenters aren't up to the Sky Racing standard (just my opinion).
