Anyone know anything about internet... cable?

[mxiu]

I've got an HDMI out and stream random stuff on my TV. I used to have digital cable, but since my roommates who I shared the bill with moved out, the service was cancelled. (Something like $100 a month... def not worth it for me alone) I want something similar to Hulu, but I live in Canada. I would be willing to pay for a service if necessary, but am looking for something beyond regular streams. Is it possible to get some HD feeds via the internet? I mainly want to finish watching the NBA playoffs in HD.

Any help would be appreciated.
