Hopefully you're close enough to the Boston market when Aereo comes to town. Aereo's service connected through a Roku box for each set gives 1hr day for free, or unlimited w/20hrs DVR storage for $8mo.
Aereo is only for OTA tv which is free. Aereo is really for those that want to watch OTA tv on their mobile phones or tablets over the internet. -- ...brought to you by Carl's Jr.
