Don't know...but if I had to guess Cox is sweating Direct TV and all the high def TV chans they are adding. All the cable monopolys are sweating bandwidth. On high def chan takes the space of 7 analog channels. Supposedly Cox was testing some new tech in September that would allow them to broadcast one chan at a time rather than all the channels simultanesously like cables do right now. Cox has stated they wanted to add 20 HD channels by the end of this year and I believe they've added about three.
Ok I believe I'm officially a high def nerd after that paragraph.
