This just happened to me and it ----s. The picture quality is quite obviously worse (which is precisely how I realized that they had done it). There are legitimate points to be made on both sides of the debate whether channels are better in 1080i or 720p, but there is NO benefit to taking a 1080i signal and turning it into a 720p signal (unless you have a 720p tv). Any modern flat screen is already going to turn a 1080i into 1080p (or better), so all this is doing is turning 1080i into 720p and then into 1080p, rather than going straight from 1080i to 1080p. This always and necessarily removes information and worsens picture quality. Any suggestion that this is beneficial to picture quality is false, plain and simple. It is bad enough that Comcast is doing this. To then have them instruct their employees to say with a straight face that this is an upgrade is really outrageous.
