I don't have Cablecom digital but I have been told by others that Eurosport 2 puts a German commentary on the game.

Eurosport 2 is also available via Sky and they have the original commentary. But they only show a 90 minute package of one game plus a one hour highlights package. And for some reason it is not in widescreen.

However, just today the AFL have announced a deal with ESPN via Sky and will start broadcast three games a week starting next Friday.

All details here.

If I wanted to watch AFL games I'd get Sky or find one of the streams that has popped up for most games this season.
