Oh you are so, so lucky! I got my Roamio 2 weeks ago today and I am still waiting to get it working correctly thanks to the fine people at Cox Cable here in Omaha!

I would be in heaven to only have spent the small amount of time you had to spend!
Cox is so unbelievably incompetent and downright greedy! We've gone through numerous cable cards, a few technicians to the house, hours upon hours on the phone and they just can't figure out why they can't get their cable cards to work properly. I've talked with Tivo and spend a lot of time in the Tivo forums troubleshooting but the issue all lies with Cox. If I can't get it working I will have to send my beloved Tivo back.

I have been with Tivo for over 10 years and was so excited to upgrade to HD and have Netflix streaming and all this fun stuff! If only I could take Cox out of the equation or had another cable company to choose from! Such a monopoly here.
Of course Cox hasn't failed to send me a bill for my cable card use in the last 2 weeks even though they've failed to send me a cable signal through the cable card!
