For a couple of months I had digital cable with Comcast, but I quit using it because the Motorola digital cable boxes managed to decrease the quality of my TV viewing experience. Comcast had an opportunity to improve this by going with a TiVo DVR, but instead it looks like they are going to try and do their own DVR using an upgraded version of the crappy Motorola platform.
