I have been trying to figure this one out but have yet to get any answers. Since you live in the Chicago area, could you more or less tell me what channels you have been able to get using the TVMini HD through your schools cable line.
I plan on getting this, eventually, and want to be sure it will be worth my money.
I go to school at UIUC, and they have Insight cable down there. Through QAM, I am able to get Fox, ABC, NBC, NBC Weather, PBS, and Tube. CBS is supposedly comming soon! I would get a few more channels (CBS, CW) if I put an antenna up, but it wouldn't be worth it.
Back in Chicago for antenna, I get a ton of channels. Take a look:
