"As a cable customer, I thought I was immune to any problems related to the upcoming digital-TV transition. But I recently discovered that cable's own migration to digital-TV transmission also has its share of headaches.
Imagine my surprise last month when I turned on the TV in my bedroom to watch a rerun of Sex and the City to discover that TBS, which had been part of my basic cable package, was no longer viewable. I clicked a few more channels and discovered that TNT was also missing. In fact, all that I am now left with on this particular TV are the basic national networks, ABC, CBS, NBC, Fox News, along with the public access station C-SPAN and WNET, my local public television station."
