Not sure if there are many fans around here but I discovered Aussie Football last year and love it. TSN shows 1 game a week usually some time in the middle of the night (most live) so PVR is your friend. It doesn't seem to be a high priority for TSN so the air times can sometimes change even as early as the day before. Schedule can be found here
