yeah ... which is better? I'm pretty sure we have the basic (normal) cable, nothing special. Not sure if we have IO or not. Maybe i'll read my bill.
HD over the air is superior quality, but limited selection. Cablevision has like 40+ HD channels.
Do you have a cable box? If you don't, you don't have iO. If you do, you may have iO but it could just be an older cable box. Do you get like TCM?
