What kind of signal will we get after Feb 09?

Yep, and higher definition too. The HD that you get from Cox isn't as high def as OTA or HD DVD or Blu-Ray. Shoot, I'd bet even a dececent upconverting dvd play passes a higher def image than what you get through Cox. Cox compresses the high def channels in order to a get a set amount of bandwidth through the cable. The more channels they offer, the more compression. If you have a local HD channel that you can get OTA and through cox, if you switch back and forth between them what you get OTA will be higher def.

I chocked on Cox when my bill exceeded $120 a month for phone, cable & internet. No HD at that time and they kept moving the channels I liked to pay tiers. When they moved Speed Channel to a pay tier, that was it!
