is your box set up properly and sending the right signal? that might explain the fuzzy text.
*shrug*
I have a scientific Atlantic box from Cox (i hate cox with a passion), it was weird at first too, but I found a thread on it over at the avs forums with tips on how to set it up properly. It looks much better now, except for the crappy hd signals from the cable company.
Phoenix is on the list for fios from verizon. The minute thats available, I'm calling up cox and getting fiber installed in the house. Faster internet and better tv quality for the same price as cable, I can't wait.
