Even 480i at 16:9 is higher-definition than what one normally gets
from a cable company.  (Although I don't know how much extra
compression Comcast does versus the original signals, and that could
make a significant difference with respect to broadcast stations.  The
cable services are all compressed by an outfit in Colorado which
specializes in real-time video compression.)  Unlike with radio,
digital TV really is better than analog TV.
