Ok, I think you're hitting two problems...

First, that is indeed an old URL you were using, and you should have been redirected automatically to the new site at
m.icetv.com.au. That redirect should be happening correctly now.
Second, there seems to be a bug on the mobile site at the moment. When you go to it for the very first time, it gets confused as to when "now" is. But if you click the time links at the bottom, or change the select lists at the top, or even just click the Search button with nothing in the search box (basically click anything to reload the guide page), it should change to "now" and show you programs in orange. From then on, it should behave correctly -- it's just a bug related to the very first time you go to the mobile site.
Let me know if you still have problems with it.
Thanks,
Russell
