Welcome to Houston.
I had a number of my family members leave Metairie except for my stuborn Great Aunt & Uncle and there insane son (85, 85 and 58yrs old) who went a few weeks without electricity and running water. Two weeks before we even knew if they were alive.
As Hdguru said, TWC provides pretty good HD service. The SA8300HD is a dual tuner DVR, if you have had TiVo you may miss a number of the features, but overall it gets the job done and the image quality from it is great on the HD and Digital SD video.
