What cable system, what if any gear they provided, how many sets and  
what tier(s) you are subscribing to.

If they provided any equipment, what maker and model #s.

A TiVo can work by controlling a STB, and can deal with scrambled  
signals that way.

Also, make sure your are set up for ntsc and the proper channel freqs  
(just checking the obvious again).
