I watched Derby Day all day on racing.com/C78. It was definitely FTA in Victoria. I switched back and forth to C10 to see how they were travelling. Didn't bother with C7.
My wife wanted to watch what we thought would have been the usual Channel 7 coverage so I tried Channel 7 (who were at Rosehill) then while the 2nd race was being run I tried Ch78 and it seemed to have the same coverage as Channel 7 in NSW. I think they were still showing Adelaide.
I said to her I'll put it on Sky1 but she just wanted to watch the fashions and all that and they had that on 78 so she was happy. I watched Sky1 up in the office.
Ironically they are saying that the Channel 7 coverage outrated the Channel 10 coverage and I reckon that is because a lot of people were expecting Channel 7 to have Melbourne on but these people (like my wife) aren't too fussed and are just happy to watch and listen to Bruce and co. As far as they are concerned the races could have been at Gulargambone and it wouldn't have mattered.
I never have any reason to watch Channel 10 so the advertising didn't reach me. Haven't watched Channel 10 since they ran Number 96 and reruns of Gilligan's Island.
