Why doesn't channel 7 show evening Aussie Open games live?

Why the heck not damnit? We're in a different state, Federer is playing and they beam it in on delay, while Foxtel goes to the trouble of showing the leftovers live to air. For all the bagging of pay TV for "taking sports away from the masses" at least they can offer the ****ing coverage when they're supposed to. Channel 7 has been a major offender for a long time - the Beijing Olympics were a disaster with several key events delayed and some not shown at all. Sorry but times have changed, it's not 1999 anymore. We should expect better, I know I damn well do.
