GPC2, if you have not already done so, I encourage you to check out the forum hosted by the New Orleans CBS affilliate WWL. There is a HD section that seems to be the main location on the Internet for posting about HD in the New Orleans market. You'll see lots of discussion there about whether it is best to go with Cox or DirecTV or Dish for HD in New Orleans. Go to http://www.wwl.com
and then click on "Forums" on the left and the click on "HDTV".
My main complaint with Cox New Orleans HD was that you had to buy the box. But the current rumor is that, starting in March, you'll be able to rent the box for like $10 a month. You still won't get WWL-HD as of now, but you will get WDSU (NBC) and WGNO (ABC). You say that you don't get WWL-HD with DirecTV, but that is only partially true. With DirecTV, you'll also want to have an antenna that will allow you to get the Over The Air (OTA) digital stations, including WWL-HD. That's what I do, and I can currently get the following stations OTA in New Orleans:
There is also a religious station that broadcasts digital but not HD, and the UPN affiliate in Slidel has a digital station but it is very difficult to pick it up in New Orleans. So as far as I'm concerned, you *DO* get WWL-HD with DirecTV in New Orleans.
On Cox, you won't get quite as many HD channels as you get on DirecTV -- for example, no HDNet and HDNet Movies -- but if I didn't already have DirecTV and was trying to make a choice right now, I'd think long and hard about Cox. And I'm sure that some day soon Cox New Orleans will add WWL-HD, and then it will be a very attractive alternative to DirecTV for HD in New Orleans.
