If you have an iPhone, iPod Touch or some similar portable device with a good screen, you can download all the CFL games now on iTunes.
They cost $2.49 each.
I just bought the Cats-B.C. Game. Very good quality, quite watchable on the small but sharp screen of my iPod Touch. Much better quality than watching TSN VOD on my computer because of internet bandwith issues.
I don't have a PVR at home, so this is a good way for me to get an archive of games.
I'm thinking now of maybe getting an Apple TV box this winter so I can watch them on TV during the long off-season.
Not for everybody, but if you're into portable devices, the price is certainly right.
Also, I noticed the Tiger-Cats radio show is putting up podcasts through iTunes. These are free.
